I haven't yet pinned down exactly what is the cause of this, but FEATURES="ccache" emerge portage bails w/ a gcc compilation failure- the problem is that it's attempting to access /var/tmp/portage/home/.ccache (which doesn't exist). You end up with errors similar to this- Checking libc version... ccache: failed to create /var/tmp/portage/homedir/.ccache (No such file or directory) ldd: ./libctest: No such file or directory rm: cannot remove `libctest': No such file or directory gcc -march=i386 -O1 -pipe -D_GNU_SOURCE -DPIC -fPIC -D_REENTRANT -Wall -c libsandbox.c ccache: failed to create /var/tmp/portage/homedir/.ccache (No such file or directory) make: *** [libsandbox.o] Error 1 This affects both running as root and sudo'ing. So far, I know the portage ebuild is affected, as is net-mail/fetchmail. I'd expect it to affect all packages, but haven't had the time to fully test it yet. emerge info.

Bug is caused by the addition of a default HOME export in environ (line 1834 of portage.py roughly)- if HOME isn't set (which across all my users and root it isn't), portage decided /var/tmp/portage/homedir will do, and ccache borks due to /var/tmp/portage/homedir/.ccache/ not existing. So, either create the directories, or nuke the setting of HOME to a default location when it's unset. I lean towards the later personally, since exempting kde ebuilds, no ebuild should be screwing w/ files in $HOME- the kde ebuilds are covered via their own HOME hacks. What does exporting the home var address/fix? Strikes me as cruft... course I have a major dislike of any ebuild thinking it should be installing things into HOME, since unless the app is smart enough to recreate it's additions to home on the fly, the additions to home are limited to a single user...
pre13 is out, closing.
