Re: PAR::Lipo?

I've had problems with PAR on OS X on the same architecture. The  
error I get when a binary built on say OS 10.3 is run on an OS 10.4  
machine is:

dyld: Library not loaded: /System/Library/Perl/5.8.1/darwin-thread- 
multi-2level/
CORE/libperl.dylib

I now need to supply my program in 3 versions, PPC 10.3, 10.4 and  
10.4_Intel. If I could merge all 3 into a Universal binary it would  
be better.
