Gen7 has no support for a LCD, so unsurprisingly no pin definitions have been setup for it.
If your trying to hack on the GLCD you going to have to create your own pins.h file
Personally I wouldn’t bother... GLCD's use to much rom (all the fonts have to be stored in there, as well as the graphics data) and when running it uses to many cpu cycles, causing blobs in your print. (if you have a 20mhz crystal, ie 25% faster than a mega2560, you may get away with it, i've not tried that combination)
