The problem is with libgd. Specifically, "glmaterial.cc" is calling some functions that it thinks should be in the libgd library, but which apparently aren't.

Question: which version of libgd did you wind up installing? The "xpm" or "noxpm" version? Try installing the *other* one (it should automatically uninstall the first when you do so) and see if those functions are defined in there.

Other than that, I have no clue. I would suggest marking this thread as solved (go to "Thread Tools" to do so), and then opening up a new thread under a title like "libgd installed, but compiler can't find some gd functions". Since the title of this thread no longer matches the problem being discussed, it's less likely that somebody familiar with libgd is going to read it...
