I have trouble installing bitarray (vers 0.8.0) on my Mac OSX 10.7.4. Thanks!

gcc does not seem to be the problem:

The setup is trying to run the command gcc-4.2, which doesn't seem to exist on your system. Verify by running which gcc-4.2 or locate gcc-4.2 (you may need to run /usr/libexec/locate.updatedb before you can use the latter command). In case it doesn't exist, simply create a symlink in the same directory in which the gcc binary resides:

cd $(dirname $(which gcc))
sudo ln -s gcc gcc-4.2

Ummm... yes. You did notice the second half of my answer, didn't you? – Ansgar Wiechers Sep 10 '12 at 12:39
Actually gcc-4.2 seems to be ok.. any idea??? I need bitarray because requested by [peach, a python package I need to implement the fuzzy-c-means algorithm. If you know any other usefull Python-tool for my goal it would be great! ] Last login: Mon Sep 10 14:31:37 on ttys000 MacBook-Pro-di-Gabriele:~ gabriele$ which gcc-4.2 MacBook-Pro-di-Gabriele:~ gabriele$ MacBook-Pro-di-Gabriele:~ gabriele$ gcc -version i686-apple-darwin11-llvm-gcc-4.2: no input files MacBook-Pro-di-Gabriele:~ gabriele$ – Gabriele Pompa Sep 10 '12 at 12:46
