Re: [gentoo-dev] what to do when an ebuild needs loads of RAM?

[Ilya A. Volynets-Evenbakh]

One thing I want to say - avoid using perl at all costs.
Even though Perl is pretty much standard on any Linux machine these days,
there are still situations where one may not want it.  For one thing, I 
don't want
to be building perl during stage building, just so that some ebuild can 
run one-line
script with it ;-)
