When PovRay is emerged with the confcache feature enabled, configure fails saying that the CFLAGS have changed. configure: loading cache ../../config.cache configure: error: `CFLAGS' has changed since the previous run: configure: former value: -march=athlon-xp -O3 -pipe -g -ftracer -falign-functions=64 configure: current value: -pipe -O3 -msse -mfpmath=sse -msse2 -march=i686 -mtune=i686 -malign-double -minline-all-str ingops -march=athlon-xp -O3 -pipe -g -ftracer -falign-functions=64 configure: error: `CPPFLAGS' was not set in the previous run configure: error: `LDFLAGS' was not set in the previous run configure: error: `build_alias' was set to `i686-pc-linux-gnu' in the previous run configure: error: changes in the environment can compromise the build configure: error: run `make distclean' and/or `rm ../../config.cache' and start over The Ebuild itself is also bugged, since this failure to configure does cause the merge process to exit abnormally. The make continues and fails. Even this doesn't cause the ebuild to exit, but continue on to installing and qmerging. The result is a povray installed ebuild with no files, and packages that depend on it, failing.
