I should have mentioned: I've been experimenting with base/projects/clang380-import (although the specific clang vintage does not seem to matter). In essence: 11.0-CURRENT as the context.

Comment 2 Raphael Kubo da Costa 2016-01-19 16:55:36 UTC

I think the freebsd-clang mkspec problem is a red herring: upstream has it in mkspecs/unsupported/freebsd-clang, we do some patching and black magic in devel/qmake5 to move it to mkspecs/freebsd-clang.

This looks more suspicious to me:

Can you try building again with WANT_QT_VERBOSE_CONFIGURE=1?

Ahh. It is another example of libcrypto.so.7 issues. . .

I can confirm that on both an amd64 context and a rpi2 (arm) one building the port that had installed /usr/local/lib/libtspi.so.1 first allowed "portmaster -DK print/qt5-printsupport" to then work.

Comment 5 Raphael Kubo da Costa 2016-01-20 09:17:23 UTC

I'm glad it worked in the end. Closing the issue now.
