Nope, that didn't do it.
The first clue I got that something is wrong was that mcrypt.h could  
not be found. Even though it exists in /usr/include. So I added the  
include_dirs and library_dirs to setup.py


mcrypt=Extension(
	"mcrypt",
	sources=["mcrypt.c"],
	include_dirs=['/usr/include'],
	libraries=["mcrypt"],
	library_dirs=["/usr/lib"],
	define_macros=[("VERSION", '"%s"'%VERSION)]
)

setup(name="python-mcrypt",
       version = VERSION,
       description = "Python interface to mcrypt library",
       author = "Gustavo Niemeyer",
       author_email = "niemeyer at conectiva.com",
       license = "LGPL",
       long_description = \
"""
Python interface to mcrypt library.
""",
       ext_modules = [mcrypt],
       )


I'm still getting the same output:
unning build

-bundle -undefined dynamic_lookup build/temp.macosx-10.3-fat-2.5/

lipo: can't open input file: /var/tmp//ccqN4eHR.out (No such file or

It makes no sense, so I went to another brand new mac, installed  
XCode and Python 2.5 and libmcrypt-2.5.8. I got the same results. So  
I'm at a loss, how can ld not see libmcrypt.

I'm digging into disutils.sysconfig to see what is the build  
environment that disutils is using.
Does anyone know how to build an extension manually? without using  
distutils. If I can get it to build outside of distutils I might be  
able to figure out what need to be done.

Thx
