I keeping the default of /Library/Tcl/macports1.0 is enough bring the 
GUI PortsManager.app back to life in good working order, then by all 
means keep the current location of @TCL_PACKAGE_DIR@ :-)

I don't understand why the external software couldn't just look for the 
module in /opt/local, if indeed nobody has no more than installation 
and never move it, but maybe it is indeed harder to do...

This is the current default, so if that's the best then do nothing / 
keep it. As noted, those who want it moved can do so either using 
configure or after the installation.

For the record, here are the default locations:
Darwin: /Library/Tcl/macports1.0
FreeBSD: /usr/local/lib/tcl8.4/macports1.0
Linux: /usr/share/tcl8.4/macports1.0

The main reason it was moved was to support packaging solutions (on 
other platforms) that only supported installing things in the 
designated prefix (e.g. /opt/local) and not in system directories 
(without choosing / as the root of the install, and supplying both the 
pats in full).

But it was *only* during this packaging process, and it was restored 
into the system location by the use of a install script and similarly 
removed again from there with a uninstall script. It doesn't have to 
affect the standard install location unless we want it to, it was just 
an idea...

PS. But for those that *do* keep it in their ${prefix}, I would suggest 
having it located at ${prefix}/share/macports/Tcl so the location 
mayhem can be kept to a minimum... :-)
