you should install instead the X11User package from the main MacOS X install disk (it is optional). Remove the symlinks before doing that. What you installed now are the libs needed to compile ROOT from source.
I thought that I did install the “X11 User package” by clicking the “install Bundled Software Only” icon. The only other thing remotely sounding like X11 is on the install disk is a folder called “Xcode Tools/packages/X11SDK.mpkg” which was done by main install.
It is a little strange that I don’t get an application called “xterm”
and
Before I put in the link to X11R6, root just complains that it can’t find the dylib
macintosh-5:~ stephanlinn$ root
