I can suggest that the tclx8.3 has a bug: its pkgIndex.tcl file has
such [package ifneeded] command which picks whatever latest version of
the shared library it finds. If there's tclx8.4 also installed, requiring
tclx under 8.3 Tcl interpreter will load the 8.4's shared library
that will probably crash on on certain Tclx commands.

I tried to run Tkabber with wish 8.3 and stomped on this issue. Tkabber
failed on some string operation.

Adding explicit version to the [package ifneeded] command in pkgIndex.tcl
solved the problem.
