please do a bit more analysis besides `grep gcc`. those things are building host tools (BUILD_CC), not target tools.
I'm not sure what kind of analysis you are expecting from me? I just only wanted to compile media-libs/netpbm using clang. I added to CFLAGS "-Oz" which isn't supported by gcc and noticed that gcc is invoked instead clang. Next I changed "-Oz" to "-O4" and started emerging once again. And I can see that sometimes gcc is invoked and sometimes clang (as you can see in build.log).
(In reply to comment #3) like i said, doing `CC=clang emerge foo` and seeing gcc being run does *not* mean there is a bug. you must look at *how* gcc is being invoked. in this case, it's because of $BUILD_CC, not $CC, being used to generate *build time* tools. those tools are not installed.
