The $PATH you set in ~/.bashrc is only valid for bash, i.e. only in the
terminal window you open.  If you start GPS from a graphical menu, this
menu does not run in your shell therefore cannot see your changed $PATH,
so neither can GPS.

For GPS to see your $PATH, two conditions must be met:

* your ~/.bashrc exports PATH (not just sets it)
* you must start GPS from bash, i.e. from a command line.

Or, simply upgrade to Debian :)
