Fixing Pyrosetta4 (new bindings) to work with Anaconda Python

gistfile1.md

This is a note on how to fix the new Pyrosetta4 bindings (which now pip install!!!) if you are using anaconda's python.

So assuming you have downloaded the latest bindings, unzipped them, pip installed them (all with anaconda's python at the front of your path).

Then, you open up python (in a jupyter notebook) and try

>>>import rosetta
>>>import pyrosetta

Unfortunately, it dies with the following error:

Traceback (most recent call last):
    import rosetta
ImportError: /home/carlin/bin/anaconda/bin/../lib/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /home/carlin/bin/anaconda/lib/python3.5/site-packages/pyrosetta-4.0-py3.5.egg/rosetta.so)

This seems to stem from the version of libgcc that comes installed in anaconda. You can fix this by updating that lib with the following line

conda install libgcc

Now import rosetta should work ( this works for both python 2.7 and 3.5 )
