Re: [Fink-beginners] re: fink doesn't detect Apple's X11 installation

[Nick B. <n.j...@el...>]

Martin was absolutely correct. There were no virtual pacakges as he 
suggests, and it turns out that reinstalling the X11 and XCode Apple 
software does indeed fix the problem.

Sorry to have started another thread about the same subject. Coming from 
a unix background, I kind of expected a package installer not to be 
lying when it said "Software installed successfully". Maybe I should 
watch the logs next time :)

The info about fink is very useful, all the same. I hope someone else 
might find it helpful.
