Cannot get webalizer-2.00.12-2 to run.

["Mike Glaser" <mikeg@tcamerican.com>]

I am having some problems with getting webalizer to run on a new RedHat 6.2 
server.

The package I installed was webalizer-2.00.12-2.i386.rpm. I downloaded it from 
rpmfind.net.

After configuring the webalizer.conf file to my liking I run the webalizer and 
was given the following error:

webalizer: error in loading shared libraries: webalizer: undefined symbol: 
gdImagePng

The program generated the folowing files:
webalizer.current
daily_usage_200007.png   <-- 0 byte file.

I thought the following packages (that are installed) would have been all that 
was required, but I seem to be missing something.
libgd-1.3-4.i386.rpm
libpng-1.0.3-2.i386.rpm
libpng-devel-1.0.3-2.i386.rpm

I tried to upgrade to libpng-2.1.0.3-1.i386.rpm, but I was told that it was older 
than the version already installed.

Can anyone tell me what I am missing?

Thanks,
