My guess would be some 3rd party compilers that don't work properly.  
Make sure you're using Xcode 2.4 or higher (2.5 is the current version  
for Tiger) and that you don't have any broken compilers (e.g. from  
HPC) in /usr/local. If in doubt rename (or delete) /usr/local and try  
again.

Cheers,
Simon
