gdImageGif is there, but gdImagePng is not. I would suggest you add
conditional configure stuff to use gdImageGif if gdImagePng is not
present. If the gif function is in a shared lib you happen to be linking
with, then it's not your licensing problem ...
Here's the relevant bit of the log:
...

Is libxml v2 available somewhere?

RPM picks up all shared lib deps automatically. In addition, you can
add dependencies on specific packages in your spec. If needed, you can
also specify a dependency on a particular version of a package (or range of
versions).
Here's a simple gensrc example:
sherman 16% gensrc pcpmon
gensrc: done. See "pcpmon/Porting-Guide" for further instructions.
sherman 17% cd pcpmon
sherman 18% ./Makepkgs
== configure, log is Logs/configure
== default, log is Logs/default
== dist, log is Logs/dist

Summary: PCPMON is a package for doing something useful.

You should edit the VERSION file to specify the version of the package
to build. To tell RPM that pcpmon requires pcp, gd-devel with version
greater than 1.3 and libxml-devel with version greater than 1.8, edit
build/rpm/pcpmon.spec.in and add something like the following after the
"Source:" tag :-
Requires: pcp >= 2.1.8, gd-devel > 1.3, libxml-devel > 1.8
