General questions on packages and package path

[Super Bisquit]

Have the packages for PowerPC32 been built yet?
If so, what would be the proper PACKAGESITE, PACKAGEROOT, and PKG_PATH
variables?
And, I have some older packages hosted on Google code. I'm not able to set
a variable because I do not know how to properly access the Google FS to
the project.

I don't know when I'll be updating the packages.
