pip3 fails to compile C module(like Pillow, readline etc) on Yosemite

After upgrading OSX to Yosemite, I found pip3 was not working on homebrewed python3. There seems to be many blogs about this problems but I should do some try-and-errors to fix. Here is what I did in order.  1. install Command Line Tools for 10.10, downloaded from Apple Developer( .  2. reinstall gcc brew reinstall gcc  3. reinstall python3 brew reinstall python3  4. do pip pip3 install pillow I am not sure this is the best way, but it worked for me at least. Hope this helps somebody.
