After emerging media-libs/libpng-1.2.43-r3 (which is in the 1.2 slot), it only merged a single file into my filesystem. Here's the output of qlist: $ qlist media-libs/libpng-1.2.43-r3:1.2 /usr/lib64/libpng12.so.0 Since it doesn't include any headers, static libaries or pkgconfig files, any packages that depend on libpng at compile-time will fail to build. Steps to repro: 1. unmerge libpng (the 0 and 1.2 slot'd versions conflict) 2. run `emerge -v =media-libs/libpng-1.2.43-r3:1.2' If you have it properly keyword'd, it should successfully build/install, but it'll only merge a single shared library, and nothing else.
And here's the output of emerge --info on the package: Portage 2.2_rc67 (default/linux/amd64/10.0/desktop, gcc-4.4.3, glibc-2.11.1-r0, 2.6.34-gentoo-r1 x86_64)
