[gentoo-catalyst] Making emerge's catalyst use a proxy

[Daniel van Ham Colchete]

Hi all!!!

here at my office I'm playing with catalyst a little bit. I already use it
to create a stage4 to my servers and tinderbox to produce update packages
for the servers.

I'm always downloading the same thing another college will download again
and our workstations will also download latter (emerge -uD world). For the
workstations we have a http proxy (http-replicator) and we have our own
rsync repository for the local desktops to download from it instead os going
to the internet.

The question is: how do I make catalyst use my proxy to download things? I
would have to change emerge's make.conf inside the package and I don't know
how to do it.

Thank you very much

Best regards,
Daniel Colchete
