I'm using sys-apps/portage-2.1.11.15 If python-mhash is not installed I have problems with following packages: app-office/libreoffice-3.5.5.3 app-emulation/virtualbox-4.1.18 Merging hangs during checksum checks and emerge process eats 100% CPU. I was waiting for 10-15 min, but no progress. Confirmed on two different boxes with different CPUs/configuration. Installing python-mhash solves problem. I think that is critical as it stops user from emerging some packages without providing any failure information.
I tested with VirtualBox-4.1.18.tar.bz2 (73688436 bytes) here and it took about 20 minutes. So, I've updated to portage dependencies to required python[ssl] or python-mhash.
Here's a fix to skip whirlpool digest checks when they're unaccelerated: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=63e25313d785f40abff3197fe0f3a3eeaa617f7d
