Make sure you have GTK installed. In case you have SuSE, the following 
packages need to be present on the SuSE 9.0 box (which are
normally not installed):

- python-gtk (bindings)
- python-numeric

Similar package requirements may apply with other distributions.

If your're still seeing problems then (and/or you have SuSE or Gentoo), 
try the attached 'bluepin' script (replace the 'bluepin' script in /bin/).


Hope this helps,

Michael
