Hi. I can't start X11 port on my OSX because package has been built for 10.2. if someone knows where I can find X11 binary package for 10.1 .. please ... let me know.
I don't think such a thing exists... Apple's X11 is dependent on features that only exist in 10.2. As an alternative you could go with XDarwin. This is what I used before Apple released theirs, and it works very well. The performance isn't quite as good as Apple's X11, but it's very usable.
