I completed a build with no obvious errors from tarballs, but I get an error
when running applications that I hope someone can help with. I am using a
debian system that began with a Knoppix HD install. The error messages are
as follows:

SystemError: wxEntryStart failed, unable to initialize wxWidgets! (Is
DISPLAY set properly?)
I am at a loss of where to look. Any suggestions?
Thanks.
