You've probably already noticed, but the cause is likely -L${LOCALBASE}/lib before local -L's, so system libleveldb is linked instead of bundled one.
There are separate issues at play here: * Our .qmake.cache hack in bsd.qt.mk doesn't work correctly with USES=qmake:outsource, as it uses ${WRKSRC} instead of ${BUILD_WRKSRC}, so it's creating the file in the wrong directly and passing the wrong value in -L. * Even after that's fixed, the way leveldb is referenced when linking libQt5WebKit.so (-L/path/to/qt/libleveldb.a's/location -Wl,-whole-archive -lleveldb -Wl,-no-whole-archive) makes ld use liblevel.so if it's available. * We should actually be using the system's leveldb anyway instead of using a bundled dependency. However, the databases/leveldb port installs memenv.h into ${LOCALBASE}/include/memenv/memenv.h instead of ${LOCALBASE}/include/leveldb/memenv/memenv.h. Qt's configuration code expects the latter, not the former, so it's never able to detect leveldb is installed.

With CONFIGURE_WRKSRC, we get the right value regardless of whether :outsource is used or not. PR: 212859 Reviewed by: tcberner MFH: 2016Q3 Changes: head/Mk/bsd.qt.mk
A commit references this bug: Author: rakuco Date: Tue Sep 27 07:08:20 UTC 2016 New revision: 422803 URL: https://svnweb.freebsd.org/changeset/ports/422803 Log: Fix some configuration test failures and use the system LevelDB port These are fixes for two separate issues (even though fixing the latter depends on fixing the former), but they are being landed together to avoid having to bump PORTREVISION twice. 1. r411689 ("Drop USES=gmake") caused a regression where several configuration tests (glx, libXcomposite, libXrender and leveldb) were failing even though they should not. The .pro files for those tests all have "OBJECTS_DIR = obj", which causes qmake to create this subdirectory when generating the test's Makefile and put object files there. The problem is that make(1) always tries to cd into this directory (among others in case MAKEOBJDIRPREFIX or MAKEOBJDIR are set), so the compiler was being invoked like this: c++ -o obj/foo.o /path/to/foo.cpp from _within_ obj/ itself, causing the compiler to fail. Readding USES=gmake is an option, but it causes the build to take a lot longer, so the approach I ended up adopting is to patch the .pro files and remove the OBJECTS_DIR lines. Fixing this enables a few more graphics-related configuration options ("graphics_surface" and "glx"). 2. The port was always failing to build if databases/leveldb was installed. Because we were not depending on databases/leveldb and also because of the item above, we were always building WebKit's bundled LevelDB copy as a static library and linking it into libQt5WebKit.so. However, the way the linker was invoked was always causing the system-wide libleveldb.so to be used instead: c++ -o libQt5WebKit.so -Wl,-whole-archive -lleveldb -Wl,-no-whole-archive -L/path/to/static/leveldb [...] Since there is no reason to use a bundled dependency anyway, it is easier to just make the build use the system-wide LevelDB. Doing so does require some patching though, as the LevelDB port installs the memenv.h header into a location that differs from the one WebKit expects.
