The .so ending is used for a dynamic library format used on the GNU/ 
Linux OS. Mac OS X uses the Mach-O format with ending .dylib.  
However, I think the functions calling these are named the same.

So I think that if the dynamic library you are calling is compiled  
for Mac OS X, just changing the ending when looking for it from ".so"  
to ".dylib" might do the trick. The Mach-O format do not support some  
things that can be used with the".so" format, so when compiling a  
dynamic library with GCC, one may have to change some option there.  
Don't know what it was, but if you get an error, it might be -- 
dynamic or something. Check at the site <http://developer.apple.com/>.
