shp2img error: stack trace

[Ryan Ollerenshaw]

I just installed Mapserver 5.0 on Fedora Core 6 with Apache 2 and PHP
5.2.4.  Whenever i run shp2img i get a stack trace:

[root at xxxxx]# ./shp2img -m /var/www/html/test.map -c /var/www/html/test.png

Here is the configure that i am using:

./configure --with-proj=/usr/local --enable-runpath
--with-geos=/usr/bin/geos-config --with-ogr
--with-gdal=/usr/bin/gdal-config --with-postgis=/usr/bin/pg_config
--with-curl-config=/usr/bin/curl-config
--with-php=/usr/local/php-5.2.4 --with-wcs --with-wfs --with-wmsclient
--with-wfsclient --with-threads

Make runs alright except for a couple warnings:

php_mapscript.c: In function ‘php3_ms_img_pasteImage’:
php_mapscript.c:6327: warning: implicit declaration of function
‘php_gd_gdImageColorExact’
php_mapscript.c:6331: warning: implicit declaration of function
‘php_gd_gdImageColorTransparent’
php_mapscript.c:6334: warning: implicit declaration of function
‘php_gd_gdImageCopy’

Any ideas on what i can do to get shp2img to work correctly?
