Failed to emerge app-crypt/gcr-3.14.0, the reason is x11-libs/gtk+ have no "X" use flag. The following is a fragment of the error message: make[2]: *** Waiting for unfinished jobs.... ui/frob-system-prompt.c:29:22: fatal error: gdk/gdkx.h: No such file or directory #include <gdk/gdkx.h> ^ compilation terminated. Makefile:4485: recipe for target 'ui/frob_system_prompt-frob-system-prompt.o' failed app-crypt/gcr successfully emerges after I execute the following command: echo "x11-libs/gtk+ X" >> /etc/portage/package.use I guess gcr-3.12.2 also has this problem. Reproducible: Always
