Hello!
Some linux distributions (as Fedora Core) do have gd library already
available. GD is also needed to build new version of pcb with gtk frontend.
The only differece between gd and libgdgeda is the direction of
drawing arcs. Libgeda can be modified to use original gd instead of libgdgeda
This requires changing only one line of C source and some modifications to
configure files.
Patch appended.
Wojciech Kazubski
