Code with BSD-like license in Parrot repository?

[Bernhard Schmalhofer]

Hi,

it was suggested by Andreas Rottmanm, rotty, to use 'riaxpander' in the 
implementation
of 'Eclectus'. riaxpander is a macro expander for Scheme. It is licensed 
in a BSD-like way,
http://mumble.net/~campbell/darcs/riaxpander/LICENCE.
Can this code be added to 'languages/eclectus' in the Parrot repository?
I know that 'Artistic 2.0' in incompatible with GPL. What's the score 
with BSD-like?

Regards,
  Bernhard
