Gentoo "emerge sync" through restrictive firewall

[Matthew Carpenter]

Here's one for the Gentoo gurus.

Trying to install my first Gentoo install, using Stage3 and installing 
through an existing SuSE 9.0 install.
I have downloaded and expanded the .tar.bz2 image onto it's own 
partition.  But emerging the kernel has become and issue.
The instructions say to chroot to the partition mount point, "source 
/etc/profile", and then "emerge sync" .
Unfortunately the "emerge sync" causes an rsync error, since rsync is 
not allowed through our firewall.  And "emerge gentoo-dev-sources" fails 
as well.

Any other ways to do this?  The documentation I have been searching does 
not show any other way.

Thanks!
Matt
