Hello,
Dealing with these python libraries gets messy. Right now you are running python out of a conda environment. But that is different from running it under fink, which is different from running it under homebrew, which is partially different from running it from a "standard" system setup.
When running conda, you would not use fink or homebrew packaging.
If you want to install PyQt4 under conda, try "conda install pyqt=4". See if that works better.
If that does not fully work please post at least the afni_system_check.py output for "python libs".
