FYI, I solved the problem building and installing audiolab on fedora. It was operator error: http://pypi.python.org/packages/source/s/scikits.audiolab/ built without a hitch once I installed two extra packages.

I didn't install 'numpy-f2py-1.3.0-7.fc12.x86_64' and only had 'numpy-f2py-1.3.0-7.fc12.x86_64' installed. Unfortunately, the error message wasn't exactly helpful until I realized numpy was only half installed from reading the numpy source file I finally realized it was dying, crypically, in (bug, IMHO). Once that hurdle was cleared, it was obvious I only had 'sndfile' binary package installed so I also installed libsndfile-devel-1.0.20-3.fc12.x86_64. With that all in-place, I followed http://www.ar.media.kyoto-u.ac.jp/members/david/softwares/audiolab/sphinx/installing.html#build  and compiled and installed audiolab. (next, trying it out).
