And yet, you caused them.  This is probably the root if your problem.   
Messing with files in /System or /usr (except for /usr/local) is a  
recipe for disaster.  There's always a better way to "replace"  
something, usually as simple as just putting /usr/local/bin (or other)  
early on in your PATH.

My suggestion:  Reinstall OS X, and don't screw it up this time.

What the heck is site-packages doing in sys.path?

You should basically never set PYTHONPATH

running $PATH?  What the heck?  If you mean typing just $PATH at a bash  
prompt, of course it's going to say no such file or directory, it's not  
supposed to do anything useful.

These lines shouldn't ever be necessary

This looks right enough.  Typically DYLD_LIBRARY_PATH is a terrible,  
awful, evil thing to do, but that's how Qt works.
