 I already have been running my script under tcl 8.6 for over a year. But I
 accept that I'll need to change the script to use MacPorts tclsh.


 Replying to [comment:3 ryandesign@…]:
 > I would love if we could find a way to fix all the Tcl scripts so that
 they use MacPorts tclsh8.5, but that the MacPorts prefix does not need to
 be hardcoded into them. For example, we already know the technique of
 having the script use `#!/bin/sh` as the first line, then re-launching the
 script under tclsh. Perhaps this technique could be modified to determine
 the MacPorts prefix programmatically (using e.g. `dirname $(dirname
 $(which port))`).

 I'm attaching a proposed patch to implement this, which works for me. The
 executable bit should also be set. If this seems acceptable, I would like
 similar changes to be made to all the Tcl scripts that need it (i.e. in
 contrib).

 I would also like to request that a tclsh symlink be created in
 ${prefix}/libexec/macports/bin so that later on, once we upgrade MacPorts
 to 8.6, we don't have to go modifying each script again to change tclsh8.5
 to tclsh8.6.
