Segmentation fault (core dumped)

I installed bsddb3-6.0.0, db-6.0.20.NC, and gdbm-1.10 on a 2.6.32-358.11.1.el6.x86_64 CENTOS6 linux server and continue to run into the Segmentation fault.  Not sure what's going on.

Sorry this issue never got attention, but Python 2.7 has now reached end-of-life and with it the _bsddb module.  As such, I'm going to go ahead and close this issue.
