building qcad

[Dennis Veatch]

Just a side note I quess. Not sure if it's a bug or what. Was running "lin 
qcad" via screen and it kept failing the build when it got to qcadlib part. 
So I killed screen and ran "lin qcad" with plain old ssh and it finally got 
past qcadlib.

So I'm quessing it's something to do with the defaults of screen, though no 
clue what to look at. 

Anyone else has this sort of problem with screen?
