LinuxQuestions.org - CentOS -- problem installing dvipng -- error: cannot find/use libpng

I just installed tetex, from which I got latex and a bunch of other stuff. My ultimate goal is to enable latex functionality on various websites. In order to do that, however, I first need the dvipng program. Dvipng converts dvi files to png's.

My problem is that when I run ./configure on the dvipng-1.9 source I downloaded from sourceforge (it's not in the repositories set for my web hosting's package manager, up2date), I get the following error (also, note that I tried downloading the package from savannah.gnu.org and got the same error):

Code:

[root@vps dvipng-1.9]# 

./configure checking whether make sets $(MAKE)... yes

configure: error: cannot find/use libpng

Yet I clearly DO have libpng, because when I try to install it through my package manager, I get this output:

Code:

[root@vps dvipng-1.9]# up2date -i libpng Fetching Obsoletes list for

The following packages you requested are already updated: libpng

So what's up with this, why can't dvipng's configure find/use libpng when I clearly have it? If you don't know the answer, can you direct me to where I can find the answer?
