[gentoo-user] Build PowerPC binary packages on AMD64?

[Mark Knecht]

Hi all,
   I know nothing about this sort of stuff so I don't know where to
even start looking. Thanks in advance for any pointers.

   Here's the setup: My desktop machine is a new, fast Core i7 980x
processor. It is capable of doing emerge -e @world (including XFCE4,
Gnome and KDE) in around 4 hours. On the other hand my MythTV backend
server is an old PowerPC which takes literally days (2? 3? 4?) to do
the same thing with only fluxbox on the system. While this was OK a
few years ago it's not something I'm enjoying much anymore. (Did I
then?)

   So, the question is can I somehow set up an environment on my AMD64
machine where I build PowerPC binary packages using emerge, ssh them
over to the Mac and then emerge them there to get the machine up to
date quickly? What do I read to understand how to do this?

   Note that it's fine to build the kernel, ymboot and machine
specific stuff on the Mac as that's very minimal.

Thanks,
Mark
