Comment 4 for bug 1309336

Thanks Bert. That got me past that issue by running:

yum install gtkglext-devel

Now onto the next issue:

...
checking for GTKGLEXT... yes
checking if GIF output from the png HID is desired... yes
checking if JPEG output from the png HID is desired... yes
checking if PNG output from the png HID is desired... yes
checking for gdlib-config... no
Cannot find gdlib-config.
Make sure it is installed and in your PATH.
gdlib-config is part of the GD library available from www.boutell.com/gd.
This is needed for the png HID. I will look for libgd anyway and maybe
you will get lucky.

checking for main in -lgd... no
configure: error: You have requested gcode, nelma, or png HIDs but -lgd could not be found

Any ideas on what to do for the missing gdlib-config?
