Why am I seeing weird "symbol not found" errors while trying to import mdtraj?

Let me guess -- you're using a Linux cluster running CentOS 5? Your system compiler is gcc 4.1?

You need a more recent version of gcc (>= 4.4). You can set the CC and CXX environment variables to point to a different compiler.

Unfortunately, installing from conda will not help you here. You must compile from source on CentOS 5 (or similar).

For Pande lab members on vsp-compute, set the following environment variables and compile from source :
```
$ export CC=gcc44
$ export CXX=g++44
$ python setup.py install
```
