error: failed dependencies: libgd.so is needed but is installed

I'm new to Linux but so far I've been able to work through all of my problems.. This one has me. I am running linux 7.2 Apache-1.3.22-2 I'm trying to install php4-4.0.6-3cl.i386.rpm I have installed the follow packages as listed in the php4 manual. zlib libpng libjpeg gd gd-devel apache mod_php4 When trying the following command to install php4: rpm -Uvh php4-4.0.6-3cl.i386.rpm I get the following error: error: failed dependencies: libgd.so is needed by php4-4.0.6-3cl So to check and make sure "libgd.so" is installed I try rpm -ql gd-devel-1.8.4-4 and get the following returned info. /usr/include/gd.h /usr/include/gd_io.h /usr/include/gdcache.h /usr/include/gdfontg.h /usr/include/gdfontl.h /usr/include/gdfontmb.h /usr/include/gdfonts.h /usr/include/gdfontt.h /usr/lib/libgd.a /usr/lib/libgd.so And see that it is installed. I have tried everything I can think of and read many newsgroups but I'm still stumped. If you can help please send email to seth@homeland.com.
