Hi List! I got a big doubt about the compatibility between Mapserver 5.6.6 and Red Hat4, because i tried to compile mapserver in this operative system and get the following  error: 
It can´t found libxpm library, necessary to gd library.

Red hat 4 doesn´t have this library!! can be compiled mapserver in red hat4  or i need a superior version of red hat?

Best Regards.
