pystamps doesn't work from the command line on OS X - IndexError

[godber]

Pystamps has an IndexError on the command line no matter what arguments I provide.

pystamps
pystamps tests/mission_data/
pystamps tests/mission_data/*img
pystamps tests/mission_data/0047MH0000110010100214C00_DRCL.IMG

The error is as follows

 pystamps tests/mission_data/1p190678905erp64kcp2600l8c1.img
Traceback (most recent call last):

Did you run pyside_postinstall.py -install? Im also updating pystamps so if there are no pds images the window comes up blank.
