Re: Using a script licensed under GPL in an application licensed under a license that's not compatible with GPL

[Alfred M. Szmidt]

   The scripts are in ruby, basically what I do is:

   require 'gpl_script'

   GplClass.do_work

   Similarly in Python I would do:

   import gpl_script

   GplClass.do_work()

   These GPL scripts are not necessary to use the application, they just
   add more functionality.

This is clearly a deriviate work, the program changes how it works if
you remove the GPLed library/script/whatever.  It also stops working
without the GPLed library/script/whatever.
