Argh, I thought I solved the problem.

It is not hardcoded: the setup.py is supposed to detect the library
extension used on the platform, and build the name of the library
accordingly (on Mac OS X, libsndfile.dylib.1):
If you have time, I would appreciate to have the mac os X library name
problem fixed. This is not difficult to fix, but I don't have easy
access to mac os X, and this kind of info is not easy to find with
simple googling. Helpful info (you can post me privately) are:
- what does python -c "from numpy.distutils.system_info import so_ext;
print so_ext" return ?
- the name of compiled libsndfile (my understanding is that under mac os
X, for the equivalent of shared , not dynamically loaded libraries, the
convention is 'lib' + library_name + so_ext + '.' + 'major version',
where library_name is sndfile, major version is 1, and so_ext '.dylib')

Are you sure you are using the version posted on the website ? Because
nframes are coerced into 64 bits integers for some time, now (actually,
that was exactly the problem related to ctypes and ubuntu, where long
long were 32 bits instead of 64).
