I have a similar problem and wasn't able to access uber_subject.py with a similar error message. After reading the message board, I also tried adding /sw/bin in front of the PYTHONPATH; however, to no avail. Specifically, within my .cshrc, the command is "setenv PYTHONPATH /sw/bin/usr/local/lib/python2.7/site-packages". Below is the output from running the afni system check. Any help is greatly appreciated, Thank you!
