x11-wm/muffin-3.2.0 suffers from an incomplete autotools test. Furthermore the ebuild does have an incomplete dependency. Reproducible: Always Steps to Reproduce: 1. build media-ibs/cluter[-X] 2. build muffin 3. missing header error Actual Results: Build failure Expected Results: Clean build/correct deps. Build dies with: core/main.c:77:37: fatal error: clutter/x11/clutter-x11.h: No such file or directory Said header is only available when clutter was build with USE="X". Muffin tests for clutter: checking for CLUTTER... yes checking for X... libraries , headers However it seems to deliberately ignore that clutter might have different build time features. This is a clear upstream bug. Furthermore muffin's ebuild has an incomplete dependency: >=media-libs/clutter-1.14.3:1.0=[introspection?] This should include a dep on USE="X" for clutter. Otherwise one could build clutter[X], muffin, and clutter[-X] afterwards. I did not have time to test this, but I assume this will exhibit arbitrary runtime errors/linking errors. Further I assume this applies to all muffin versions <=3.2.0 (did not have time to test this yet.
