Summary: Inconsistent behavior for featurize on desktop Linux

Initial Comment:
Revision: 701

Description:

A new regression test has been introduced that creates feature vectors for 50 PDB files. The output for these files is consistent between Mac OS X and "cluster" Linux (FC11). It is inconsistent between Mac OS X and "desktop" Linux (FC8). 

How to Repeat:

1. Checkout and build r701 on Mac OS X and desktop Linux
2. Run "make regression"

Repeatability: 100%

Notes:

The OS platform response pattern suggests that it could be a rounding error in featurize, but this is not known for certain.
