Hi, I was attempting setting up picture language. I build a git tip version and applied the patch to src/6001/pic-read.scm mentioned in [1]. I downloaded the source files from [2] and modified some file paths according to my settings. Loading psgo.scm seems no problem because three empty windows pop up. But (paint g1 founder) fails. Debugger displays following message:
