I followed the indications for OSX on https://github.com/serge-sans-paille/pythran But I get the following errors: Satellite:Pythran Olivier$ pythran all_pairs.py Couldn't import dot_parser, loading of dot files will not be possible. WARNING: Disabling color, you really want to install colorlog. CRITICAL: By Jove! Your environment does not seem to provide all what we need E: I can't find a shared library for libgomp, you may need to install it or adjust the LD_LIBRARY_PATH environment variable. I could not find clear indication of what is wrong with dot_parser, googling around. which libgomp shows nothing and I could not find libgomp with brew / brew cask. My python in Anaconda 2.1 Pythran is not the easier to install and set up till now, but it seems to have a very interesting potential, so I insist, and would be grateful for some help. Thx Olivier
