problem when installing macports

Actually I meant platform cross-compiler rather than architecture 
cross-compiler, but it doesn't matter much...

It probably just wasn't updated since it really was the required one...
Like Ryan says, Mac OS X 10.3.9 (with Xcode 1.5) is also still OK to 
use.

Mac OS X 10.4.10 (actually Xcode 2.4.1) comes with *four* compilers,
one for each version of Mac OS X: gcc2, gcc3, gcc-3.3 and gcc-4.0
The recommended one is gcc-4.0, since it can't build Universal binaries
with the gcc-3.3 (and since GCC 4 is much better than GCC 3 anyway, but)

Usually you just install the "XcodeTools.mpkg", instead of individual 
pkg ?
And that will install *both* of gcc4.0.pkg and gcc3.3.pkg, by default...
