hot damn! DRIVERS_LIST: gd;mem;null;ps;svg;xfig;xwin DEVICES_LIST: gif;jpeg;png;mem;null;ps;svg;xfig;xwin
So, what did I do? Scientifically, I can't report exactly what I did that caused the above to build, but the general drift is -- my gd might have gotten linked to X11R6 detritus, and so might have been the case with fontconfig. I renamed X11R6 crap, rebuilt fontconfig, rebuilt libgd (having rebuilt libjpeg and libpng as well). Then... well, read on... On Thu, Jul 1, 2010 at 9:04 PM, Alan W.

I followed your advice and turned off most things (other than bogus languages that I have no time nor patience for). Well, it still didn't work. In fact, cmake didn't even try looking for gd. So, I guessed cmake needed a nudge, and since I had rebuilt most everything, I ran cmake again, once again with my kitchen sink of options. This time... it worked! It is still not picking up Cairo and AGG, but heck, I am going to crack a beer and celebrate for now. Enough of installation crap. Time to actually make some pretty pictures. Thanks all. Couldn't have done without you all. Go get a beer. Grill a tofu.
