`./pants` does not work out of the box - no `requests-sessions` about fsqio

Hello, John, how's things : )

Sooo...I had this whole thing where I was asking you what OS you were running and all that....but I see the issue. We thank you in our bootstrap script because that script is basically identical to your pants setup script you made. Since you already have ran that script for 0065, you already have a 0065 virtualenv in your home directory so it never installs the FOURSQUARE_REQUIREMENTS. I will push an update to the bootstrap scripts soon but the fix is generally to just differentiate upstream pants virtualenv from the fsqio one.

A random contributor to Fsqio (patrick) feels pretty strongly we should keep the virtualenv under the repo root, I guess this is an argument in his favor : )

On the plus side, you inspired me to go out and test this on some Linux images. I will update the README but you will need python-dev, JDK8 and libpq-dev and perhaps build-essential to run on linux. I will ping/close this issue when I push the fix, but you can probably get around this by passing PANTS_HOME to a location under the buildroot.

I think we have the fix for this pushed...thanks for the report!
