Yeah, the configure code was orignally set up to find Tcl linking information,
and it does so either by running tclsh or taking the tclConfig.sh file. That
was all; no tclsh was actually necessary.

The fact that the pltcl_*mod programs use the discovered tclsh setting as well
was most likely an afterthought that was not made fully robust in the fact of
all the ways that configure could be called.

By the way, these programs start with

package require Pgtcl

but we don't provide that library. Should that bother us?
