Inkscape as non-root? (-> gnome-vs -> gconf -> policykit -> fail)

[Kevin Reid]

I run MacPorts as a dedicated non-root non-admin user. Attempting to  
install Inkscape eventually installs policykit, which fails because it  
tries to create a user. What should be changed in order to be able to  
use Inkscape without any users or other administrative changes involved?
