gdImageGifAnimAddPtr undefined problems trying to build perl GD
I had quite an unexpected amount of trouble installing the perl GD package on this server. First, I needed to install libgd-devel: the makefile generator didn't notice none of the includes were around. Then I kept getting an undefined symbol:
when trying to load the GD.so during "make test"
The workaround was to disable support for animated GIFs in the configuration. My libgd version is 2.0.28, I guess that must be too old.
