[gentoo-alt] disabling inter-process-communication in the bootstrap script

[Timo Kluck]

Hi all,

I've noticed that the bootstrap script for portage prefix and its
ebuild both disable inter-process  communication for emerge. That's a
good thing, too: it deadlocks on MacOSX (both 10.6 and 10.8). However,
this also means that there is no parallel build feature on that
platform -- that is, emerge --jobs N does not spawn several jobs.

Did anyone ever manage to get this kind of parallel build working on MacOS?

Relatedly: since this works fine on other platforms, does it make
sense to have a variable in make.conf that controls this feature? The
current approach just patch portage's source files, which is slightly
less pretty.

Thanks! Timo
