php 4.0.6 and GD

Hi, I am just trying to install php 4.0.6 on redhat 7.1 so that I can use the new GD library functions. I first downloaded and installed the newest GD libraries (2.0.1 beta) and installed them. I presume that this worked OK because I didn't get any errors. I also made sure I removed the rpm of an earlier version of the gd libraries from the computer to avoid conflicts. I installed GD ("make install") and it seemed to go OK, no errors reported and seemed to copy the file to the right place... Then I configured php: ./configure \ --with-apxs=/usr/local/apache/bin/apxs \ --enable-track-vars \ --with-config-path-file=/etc \ --with-mysql=/usr/local/mysql \ --with-gd \ --with-jpeg-dir=/usr/lib \ --with-xpm-dir=/usr/X11R6 I found that I needed the last two arguments so that configure didn't throw an error, which it doesn't. But when I try and make php I get this error: . . . gd.c:95: conflicting types for 'gdIOCtx' /usr/include/gd_io.h:previous declaration of 'gdIOCtx' make[3]: *** [gd.lo] Error 1 . . . That error causes make to stop and prevents me from installing php... Has anyone got any ideas on how to avoid this? If I compile and leave out --with-gd then it makes fine... But I'm upgrading because I want to use the new image functions! Any help or suggestions would be much appreciated, tia, Kelvin.
