While trying to bump app-emulation/libvirt-glib I hit this problem:

Maybe "ln" should be called with "-f" option

Reproducible: Always

This error should be impossible. Possibilities I can think of:
1. you had FEATURES=keeptemp or keepwork, and forgot to delete /var/tmp/portage/app-emulation/libvirt-glib-0.1.2 after a failed or interrupted emerge.
2. one of your vala slots installed multiple libvala-$SLOT.pc files. (Please check by looking at "ls /usr/{share,lib}/pkgconfig/libvala*")

[Comment 3 Alexandre Rostovtsev (RETIRED) 2012-09-29 13:12:02 UTC]

Never mind, I see what happened: "use vala && vala_src_prepare" needs to be in src_prepare, not in pkg_setup.

Yeah, sorry for the noise
