Can't install plpython on Windows 8.0

I just tried using createlang to install plpython into a database on my
Windows 8.0 installation and continue to receive the error below. The file
plpython.dll is in exactly the location specified below as well. What
exactly am I doing wrong here?

createlang -e -U postgres plpythonu junk
Password:
SELECT oid FROM pg_language WHERE lanname = 'plpythonu';
SELECT oid FROM pg_proc WHERE proname = 'plpython_call_handler' AND
prorettype =
 'pg_catalog.language_handler'::regtype AND pronargs = 0;
CREATE FUNCTION "plpython_call_handler" () RETURNS language_handler AS
'$libdir/
plpython' LANGUAGE C;
CREATE LANGUAGE "plpythonu" HANDLER "plpython_call_handler";
createlang: language installation failed: ERROR:  could not load library
"C:/Pro
gram Files/PostgreSQL/8.0/lib/plpython.dll": dynamic load error

Thanks,
Steve
