You better want to try prefix-launcher[1] to bootstrap Gentoo Prefix on
AIX. Use the wiki pages [2] as starting point.
Also you might want to use prefix-launcher from svn[3] instead of the
release tar-ball, as the latter most likely has outdated package
versions.

Unfortunately I didn't test it recently myself, so it might be broken
ATM, partially maybe because of outdated versions, sorry - but you're
welcome to test it on AIX ;)
But AFAIK, mduft used svn/trunk on Interix recently...

Any of xlc or gcc-3.3.2 should be sufficient to bootstrap gcc, but
prefix-launcher should do that for you.

xlc is found as /usr/vac/bin/xlc here.

Better not - gcc claims to not use GNU binutils on AIX, so for me,
cross-compiling for AIX is not an option at all, although I've heard
some people doing that.
