It seems as though you have a hung process holding a lock on sys-apps/util-linux-2.24.1-r3 build directory in PORTAGE_TMPDIR. You should search for the hung process and kill it. You can use 'lsof | grep /var/tmp/portage' to locate the hung process. If you can't find a process with lsof, then it could be a stale "hardlink" lock that you you can clean up with this command: /usr/lib/portage/bin/clean_locks /var/tmp/portage/sys-apps However, clean_locks is only relevant if the file system mounted on /var/tmp/portage does not support "regular" file locks.
Thanks! It turns out that all it was was a suspended instance of emerge which I completely lost track of. It would be nice if emerge showed that it was waiting for a lock to clear. I remember other instances where it has said that it is waiting for a lock on the portage database or such. I changed the bug to be an enhancement.
