It was preinstalled. But I'm looking for a screw-driver to replace the
hard drive, so I'll have to install it anyway.

I know about Rosetta, but I also thought that if we figure out how to
"properly" cross-compile, it might be a bit easier to also compile
64-bit binaries on 32-bit machines etc.

I didn't know that. I only had support for 10.4 on 10.5, so I was
surprised to learn that 10.4 was still available.

I remember that I compiled TeX binaries on Leopard and people started
complaining that they were not able to use them on Tiger.

Do you have any idea how to cross-compile XeTeX (with export

I have already committed the luatex for i386. Feel free to commit the
binary for ppc and 64-bit (that need a new directory structure first),
but make sure to use

The building script needs to be adapted anyway. (Some scripts in SVN
have been modified already, but not all of them yet.)
