Depending on the OS, they may/will have different search paths for loading of libraries.  From a page I posted a while ago...

   A few general comments about ctypes
   -----------------------------------
     ctypes will look in various locations for shared libraries 
     but where can vary by platform.  Libraries in /usr/lib are 
     pretty much guaranteed to be found, but that may not be the 
     best place for your compiled libraries.  Personally I prefer
     /usr/local/lib.  Regardless of where, you may need to set 
     and export a load library path appropriate to your platform.
       LD_LIBRARY_PATH     Linux
       DYLD_LIBRARY_PATH   Darwin
       SHLIB_PATH          HP-UX
       LD_LIBRARY_PATH_32  32-bit Solaris
       LD_LIBRARY_PATH_64  64-bit Solaris

I hope this helps...  Larry
