After poking around in the source I think the error happens because the 
default file doesn't exist and the error isn't being handle properly. If 
I cd to the rl_accel folder then run

python -c "import pyHnj; pyHnj.Hyphen('hyphen.mashed')"

the error message (and presumably the error) doesn't happen. I'll try 
and fix up the code to be more discriminating and raise a proper exception.
