Psycopg2, pymc, theano and DYLD_FALLBACK_LIBRARY_PATH

I can not use pymcwith psycopg2. The following is a simple passage from a tutorial:

import pymc as pm
with pm.Model() as model:
    x = pm.Normal('x', mu=0., sd=1)

results in the following error:

Exception: the environment variable 'DYLD_FALLBACK_LIBRARY_PATH' does not contain the path '/ Users / josh / anaconda / envs / py27 / lib' in its value. This will cause Theano not to compile c-code. Update 'DYLD_FALLBACK_LIBRARY_PATH' to contain the specified value, this will fix this error.

I managed to fix this problem by adding:

export DYLD_FALLBACK_LIBRARY_PATH=$DYLD_FALLBACK_LIBRARY_PATH:/Users/josh/anaconda/envs/py27/lib

to my shell source file .bashrc. However , and this is the part that I do not understand, this line breaks psycopg2:

---> 50 from psycopg2._psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID
     51 
     52 from psycopg2._psycopg import Binary, Date, Time, Timestamp

ImportError: dlopen(/Users/josh/anaconda/envs/py27/lib/python2.7/site-packages/psycopg2/_psycopg.so, 2): Library not loaded: @loader_path/../../../libpq.5.dylib                                                                                                 
  Referenced from: /Users/josh/anaconda/envs/py27/lib/python2.7/site-packages/psycopg2/_psycopg.so
  Reason: image not found

How can I psycopg2and pymc(here theano) live happily together?
