So, despite the assurance from ./configure that PNG output is=20
enabled, there is no actual driver information (the gd.rc is empty).

What happens if you edit this file and insert the following lines:
jpeg:JPEG file:0:gd:40:jpeg
png:PNG file:0:gd:39:png

(Not sure about the meaning of the numbers, but you can try=20
anyway)

We can then start speculating from there.=20
