Cannot install lscsoft-glue through setup.py

@ryan.fisher As encouraged by @duncanmmacleod we want to retire the PyCBC clone of glue (pycbc-glue) and use this official version of glue in PyCBC. However, we currently have a couple of problems that are not allowing us to do this.

Here is a less critical issue than #5 (closed):

When running python setup.py install in PyCBC dependencies are automatically installed if not present based on them being listed in the setup.py file. However if we add lscsoft-glue to the requirements in PyCBC's setup.py file we see:

Not all of this makes sense to me, but it looks like the .sh file is somehow causing a problem!
