This is an ongoing issue, with the most recent thread being: https://marc.info/?l=pkgsrc-users&m=156108314821058 There's a wiki page: https://wiki.netbsd.org/pkgsrc/gcc/ The quick fix, which isn't, is to set GCC_REQD=5 but then if another package uses the library it'll fail to link if it's compiled with an older compiler. This happened with print/popplar. There have been patches with structural fixes. Sijmen
