I release one of the projects from work as a universal binary on OS X. Up until tomorrow that mean just i386 and ppc. With snow leopard, it looks like it’ll be a good idea to support the 64-bit architectures as well, especially considering its an ODBC driver I’m working on and the native apps running at 64-bit will want to talk to it that way.
Since we used a lot of open source libraries to save us time, I need to have those built super-universal as well. The first one I tackled was curl, which had some issues due to configure, so I had to write a shell script to do the hardwork for me. It needs to run configure three times, and I got a lot of the information for it from http://curl.haxx.se/mail/lib-2009-05/0000.html.

There will be more of these as I build the other dependencies.
