How are you compiling them? I don't see how you can get either .a  
or .dylib using R CMD SHLIB, so my guess is that it has nothing to do  
with the compiler but with the way you compile the sources. On OS X  
package libs are neither dynamic libraries (.dylib) nor static  
libraries (.a) - they are bundles. The compilation shouldn't matter  
and if in doubt you should be able to use gcc for the linking step in  
case the IBM compiler is not compatible.

There is no converting, you should get the right .so directly  
otherwise you're doing something wrong. Please tell us more precisely  
what you're doing.
