Some that you may find are: /lib/libm.so /lib/libsocket.so /lib/libpthread.so /lib/libnsl.so On a side note, we have a question about this in our prefix-ebuild-quiz[1] (question 5 from the second section). > grab an unsuspecting dev trying to make his ebuilds prefix compliant?

I think there's unfortunately no simple way to tell what should be in and what unfortunately has to be out. It depends a lot on the host system. I feel -- but I can't back this up with hard evidence -- that it are usually the libs that are not in *DEPEND that can only be available in the host system. Basically because they usually are part of the libc, which we assume to be installed. [1] http://dev.gentoo.org/~grobian/prefix-quiz -- Fabian Groffen Gentoo on a different level
