Nope, don't see any problems...
Mind that if you compiled some of the libs yourself these usually end up in
/usr/local/lib, while installed libs are in /usr/lib. If you compile a lib
yourself you should first remove the installed (redhat) lib package (rpm -e
libxxx), otherwise probably the old installed version would still be used,
which can (and will) lead to errors. Or configure any libs you compile to get
installed in /usr/lib (--prefix=... configure option). But as shp2img runs
fine, I don't think you have a problem like this.
However, you could check just to be sure... there should be no libraries in
/usr/lib that are also in /usr/local/lib.
I'm no regular user of the cgi version of mapserver. Usually use
php_mapscript. Maybe someone with more mapserver cgi debugging experience can
say something about this?
Cheers,
Vincent.
