For me, it helped to uninstall old multimedia/qt5-multimedia before build and reinstall the new one.
(In reply to Rainer Hurling from comment #1) Deinstalling the port first worked for me too.
The error likely comes from GStreamer's pkg-config files passing -L/usr/local/lib to the linker before -L/usr/ports/multimedia/qt5-multimedia/work/qtmultimedia-opensource-src-5.4.1/lib, so existing QtMultimedia libraries end up being used instead of the ones being built. This was supposed to have been solved when we fixed bug 194088, but the pkg-config case was not taken into account. The only way to solve this once and for all is to fix 195105.
A commit references this bug: Author: rakuco Date: Mon Dec 28 18:51:42 UTC 2015 New revision: 404694 URL: https://svnweb.freebsd.org/changeset/ports/404694 Log: Make sure ${WRKSRC}/lib is passed before /usr/local/lib when linking. This is another shot at fixing the linkage problems that have plagued our users particularly when upgrading from Qt 5.x to 5.(x+1). Quick recap: in Qt5, qmake will by default pass QMAKE_LIBDIR to the linker before other directories such as ${WRKSRC}/lib, which is where the port's libraries are built. When a user is upgrading Qt, we can end up with the following linker line: c++ -o SomeBinary -lfoo1 -L/usr/local/lib -L${WRKSRC}/lib -lfoo2 -lfoo3 If libfoo2.so is being built by the port and an older version is currently installed on the system, /usr/local/lib/libfoo2.so will be picked up instead of the newly-built ${WRKSRC}/lib/libfoo2.so. At best things just work, at worst SomeBinary needs some new symbol that is not present in the old libfoo2.so and linking fails. Case in point: bug 198720. The previous approach, adopted when fixing bug 194088, was to stop setting QMAKE_{INC,LIB}DIR in the FreeBSD mkspecs and set the CPATH and LIBRARY_PATH environment variables in Uses/qmake.mk. This way we just did not pass -L/usr/local/lib to the linker at all and things mostly worked. However, people using Qt to build their own software without the ports tree were out of luck, as they would then need need to deal with passing /usr/local/{include,lib} to the compiler/linker themselves (bug 195105). Not only that, but if a dependency mentioned /usr/local/lib we would still have problems anyway (in bug 198720, the GStreamer pkg-config files contain -L/usr/local/lib, for example). We now solve the issue by setting the QMAKE_LIBDIR_FLAGS variable in .qmake.cache to ${WRKSRC}/lib instead. qmake appends the value of QMAKE_LIBDIR to QMAKE_LIBDIR_FLAGS, so we are always sure -L${WRKSRC}/lib will come before -L/usr/local/lib in the linker options. Moreover, qmake is smart enough to automatically call sed(1) and remove references to ${WRKSRC}/lib from .prl and .pc files when installing them.

A commit references this bug: Author: rakuco Date: Wed Dec 30 14:03:43 UTC 2015 New revision: 404856 URL: https://svnweb.freebsd.org/changeset/ports/404856 Log: qmake5: Set QMAKE_{INC,LIB}DIR_OPENGL. Follow-up to r404694. When we stopped setting CPATH and LIBRARY_PATH, some Qt5-based ports (astro/stellarium, audio/musescore, audio/cantata, irc/quassel, deskutils/owncloudclient) broke because the QtGui headers end up bringing in GL/gl.h, but -I/usr/local/include was no longer being passed to the compiler. This is generally caused by QMAKE_{INC,LIB}DIR_OPENGL being empty, which leads to some parts of Qt5ConfigExtras.cmake.in being left out when being processed into Qt5ConfigExtras.cmake. Specifically, the bits of code that make the directories containing GL/gl.h and libGL.so a dependency of the Qt5::Gui CMake target were not present. Fix it by setting those two variables again like we also do in devel/qmake4. Most ports broken by r404694 are fixed by this change, but not all: * audio/cantata: Accidentally fixed by this change. Upstream includes the TagLib headers wrongly. `taglib-config --cflags' returns -I${LOCALBASE}/include/taglib, but the code references headers as <taglib/foo.h> instead of <foo.h>. * multimedia/obs-studio, textproc/sigil, x11/antimicro: Those remain broken, linker calls pass -lfoo instead of /path/to/libfoo.so, and they were only working because we were passing LIBRARY_PATH to the linker before. They need to be fixed separately. Thanks to antoine@ for the fallout heads-up.
