1. emerge -1v libbsd
2. emerge -1v talloc
talloc looks for libbsd, finds it and tries to use it. Then fails to build with some in-header conflicts :). The conflicts may be libbsd's fault but the automagic dep is definitely talloc.
Ok, it seems that the build failure was due to distcc.

Successful build log
This one proves that it links to libbsd :).
