--- Comment #18 from dennis <drac...@gmail.com> --- It is fixed now!! The problem is indeed the missing patch-conf file in /usr/ports/graphics/libmng/files. I added the missing patch-conf file into libmng/files, did a make deinstall, make clean, make install in libmng. Then went back to qt5-imageformats and did a make clean, make configure, make, make install. It built and installed cleanly. This also fixed a problem in gimp-app which also failed for a problem with libmng. I think can be marked as closed. Thanks everyone who helped track this down. -- You are receiving this mail because: You are the assignee for the bug. You are on the CC list for the bug.
