PIP dependencies do not get identified as installed

[jacobagilbert]

I was writing a simple recipe to install pyserial via PIP, and discovered that even though pyserial was installed via PIP during the binary install phase, it was not detected and a source install was attempted (which failed as the recipe does not have a source install option).

Recipe pyserial.lwr:

category: baseline
satisfy:
  pip: pyserial >= 2.7

Obnoxious mode provides output:
