MapServer incompatibility with RHEL4/CE NTOS4.2

[Steven Bowden]

No Problems with mapserver-4.6.2 on CentOs 4.2 here on a Dual Code AMD 64 
running 32bit;

I am using
proj-4.4.9
gd-2.0.33
gdal-1.3.1
geos-2.2.1
mapserver-4.6.2
php-4.4.0

gcc 3.4.4
glibc-2.3.4-2.13
freetype-2.1.9-1

Mapserver config
./configure --with-postgis --without-tiff --with-jpeg --with-threads 
--with-proj=/usr/local --with-gdal=/usr/local/bin/gdal-config 
--with-php=../php-4.4.0 --with-gd=/usr/local --with-freetype=/usr/bin 
--with-ogr=/usr/local/bin/gdal-config --with-wms --with-wfs --with-wcs 
--with-geos=/usr/local/bin/geos-config --enable-debug

Regards
Steve
