Right, John Stone is aware that he needs to change the disk image for
the next Mac builds. :-)

We are also aware of this problem, but haven't got around preparing a
new build addressing it yet. According to John, we need to fix the
plugin builds so they use the path-relative Tcl library if they are
compiled against the VMD Tcl library rather than the system-provided
one.

Please wait until a new Mac build is posted on biocore. Or, if you
can, give the Linux version a try for now.

Thanks,
Leo
