Looking at the dl docs I see:

"""
Note: This module will not work unless sizeof(int) == sizeof(long) == 
sizeof(char *) If this is not the case, SystemError will be raised on 
import.
"""

That explains why it is not there for 64bit.

Docs for sys.setdlopenflags():

"""
setdlopenflags(  n)
  Set the flags used by the interpreter for dlopen() calls, such as when 
the interpreter loads extension modules. Among other things, this will 
enable a lazy resolving of symbols when importing a module, if called as 
sys.setdlopenflags(0). To share symbols across extension modules, call 
as sys.setdlopenflags(dl.RTLD_NOW | dl.RTLD_GLOBAL). Symbolic names for 
the flag modules can be either found in the dl module, or in the DLFCN 
module. If DLFCN is not available, it can be generated from 
/usr/include/dlfcn.h using the h2py script. Availability: Unix. New in 
version 2.2.
"""

Try this:

     import sys,DLFCN
     sys.setdlopenflags(DLFCN.RTLD_NOW|DLFCN.RTLD_GLOBAL)

cheers,
