I'm evaluating the project you submitted for approval in Savannah.

Your project requires proprietary software and cannot be hosted on Savannah for this reason.

Indeed, gpc is released under this license:
           This software is free for non-commercial use. It may be copied,
           modified, and redistributed provided that this copyright notice
           is preserved on all copies. The intellectual property rights of
           the algorithms used reside with the University of Manchester
           Advanced Interfaces Group.

           You may not use this software, in whole or in part, in support
           of any commercial product without the express consent of the

           There is no warranty or other guarantee of fitness of this
           software for any purpose. It is provided solely "as is".
which is non-free.

Savannah is willing to provide resources and time to developers writing Free Software that can be used without the need to ask permission from proprietary software vendor.

Besides, the author uses the vague term "intellectual property" regarding the algorithm, which makes me wonder whether his university registered a patent for it.

I think the wisest choice is to contact the gpc author and ask him and his university to re-release gpc as free software.

-email is unavailable- can provide help for this.

If, someday, you get free of this proprietary dependency, do not hesitate to resubmit your project.

Thank you for your understanding.

  GPC-Haskell - A Haskell port for the GPC library
GPC-Haskell is a haskell port for the GPC library, that implements a lot of polygon functions, such as union, intersection, difference and xor. It uses the c2hs tool to process the interface between C (the language in which the original GPC library was written) and Haskell. The source code is written in esperanto and it's available at http://www.dcc.ufmg.br/~marcot/gpc-haskell/ . It still does not work with c2hs but it's almost workable, and should be soon.

Other Software Required:
  c2hs ( http://www.cse.unsw.edu.au/~chak/haskell/c2hs/ )
ghc ( http://www.haskell.org/ghc/ )
gpc ( http://www.cs.man.ac.uk/aig/staff/alan/software/index.html )
And all that these depends.
