Before Mavericks, I was stupid (and lazy) enough to use the system Python, so my site-packages folder was completely destroyed on OS upgrade and instead of restoring a backup I decided to finally switch to home-brewed 2.7.5.

Installing numpy/scipy/matplotlib can be pretty tricky because of non-standard homebrew library locations (for stuff like gtk+, freetype2 etc), so you're better off using this http://github.com/samueljohn/homebrew-python and http://github.com/Homebrew/homebrew-science for all your scientific needs. By the way, Qt, Numba and a couple of other libraries seemed to get broken (upstream) in Mavericks, but I guess that wouldn't take too long to fix.

Also, upgrading homebrew libraries on Mavericks requires reinstallation of the entire dependency tree (because newest clang uses the newer libc++ instead of libstdc++).
