I think that error message is kinda clear. Maybe I will write some warning that
if you are on Ubuntu then you have to install dialog. Anyway it is evil that there
are Linux distros that not install dialog by default since it was meant to be a
simple tool for writing some basic scripts like netconfig etc. in a comfortable
way so it kinda defeats the purpose of dialog.
And about laters CVS, it won\'t connect to official server because netversion
has been changed long time ago (at 22.05.05), the latest source I managed to
get to work properly is 19.05.05 (CS/CEL/Cal3d/PS) which is also mirrored at
http://planeshift.xpam.de/ so you may download it from there too.
