The very latest portage available on Gentoo Prefix for Mac OS attempts to prevent packages from colliding (i.e. overwriting each others' files) by checking at install time if installing files would overwrite existing files. Whether or not the files belong to a Gentoo package, if the files already exist, portage will refuse to install over them. There is no way to get around this, because there is no way to tell portage to force installation. Unfortunately, dev-lang/perl-5.12.02 (and possibly other versions) bypasses the normal installation mechanism and installs its files itself directly into the prefix, instead of installing into a destroot which is then copied into the prefix (like usual). (You can see this happen by reading the log; it shows the files being installed directly into the prefix.) This sets off portage's collision detection mechanism; because perl's files are already installed, but not registered to a package, portage refuses to finish installing. Reproducible: Always Steps to Reproduce: 1. Install portage-2.2.01.17304. (Might happen with other portage versions, but I only recently started seeing this behavior.) 2. emerge perl Actual Results: Perl compiles, but does not finish installing because portage detects a file collision. Expected Results: Perl should finish installing.

what are the collisions you see? You can disable portage's collision-protect feature by exporting FEATURES="-collision-protect" preferably temporarily only for the package you need to merge in question
Created attachment 256251 [details] Build log for dev-lang/perl-5.12.2-r4 Here the build log, and, before I forget, the output from emerge -pqv: [ebuild N ] dev-lang/perl-5.12.2-r4 USE="berkdb gdbm ithreads -build -debug -doc"

I'll give it a shot.
I'm affraid it's not perl installing stuff outside the destroot, but more a failed/incorrect previous installation of your current perl.
(In reply to comment #4) > I'm affraid it's not perl installing stuff outside the destroot, but more a > failed/incorrect previous installation of your current perl. That thought crossed my mind, but then I saw in the build output what I thought was perl installing stuff straight into the prefix. I guess that output is somewhat misleading. I wonder how this happened. I even unmerged perl (emerge --unmerge perl) because of this. I'll bet portage's database of installed packages and their files got corrupted somehow. In any case, this is yet another bug that wasn't.
