The main change I want to make to auto_path is to add /usr/lib/tcl8.4
(or /usr/lib64/tcl8.4 on x86_64) to the auto_path so that extensions can
be installed in either %_datadir or %_libdir and still be found.  This
won't impact existing extensions because their installation directories
would still be part of auto_path.

When tcl 8.5 is available then we can look at removing some directories
from auto_path (namely /usr/lib and /usr/share) to speed up the initial
startup time for Tcl applications.  But this is a more invasive change
that will require patching almost all of the current Tcl extensions.

For now, adding %{_libdir}/tcl8.4 will be a good intermediate step that
will allow extensions to slowly migrate to the proper tcl-specific
install directories before we remove the generic /usr/share and /usr/lib
 from auto_path.

With your permission I'll update the tcl package in CVS to use this
extra auto_path directory.
