Joe,

The FWTools kit takes great care to not affect anything else on 
your system.  It keeps all it's dependencies local to the FWTools
tree and uses cover scripts to force use of it's local copies of
stuff like python when you run FWTools apps. 

What you may need to avoid is sourcing the fwtools_env.sh
script in your normal shell startup file if you want to avoid 
entanglements. 

BTW, the FWTools "install.sh" script does not move anything
outside the FWTools tree.  It just creates a bunch of internal
scripts with the path to the FWTools tree properly set, and 
compiles the python .py files to .pyc within the FWTools tree.

Despite other shortcomings, I believe that FWTools is very good
about not interacting with the rest of the system. 

I would add that similar care has been taking on Win32 though
the issues are slightly different there. 

Best regards,
