how to make sure that ProofPower bin directory comes before the system bin

PATH environment variable.


Easy - by doing exactly that before you run xpp, e.g.

  PATH=/home/sarah/pp/bin:$PATH

Put this in

  /home/sarah/.bash_profile

to have this done automatically when you log in. (That's for Fedora, at leats. For other Linux distributions, it may go elsewhere e.g. .bashrc - I don't know.)
