I have MP tcl 8.6 built in a prefix (/opt/macports-test) not in PATH and when I build base using this tcl the required tcl packages (msgcat) are not found.

$ CC=gcc-4.2 TCLSH=/opt/macports-test/bin/tclsh ./configure --prefix=/opt/local --with-tcl=/opt/macports-test/lib --with-tclinclude=/opt/macports-test/include --with-tclpackage=/opt/macports-test/lib 1>/dev/null

Though tclsh directly seems to find msgcat:
$ echo 'puts $tcl_version;package require msgcat;exit 0' | /opt/macports-test/bin/tclsh
8.6

Is the base build system removing some env var that tclsh uses to find packages?

Does anyone more familiar with tcl or MP base's build system have any light to shed?
