tcl/FreeBSD 4.2-STABLE, multiple TCL versions installed

Trying to compile current sources using:

./configure --prefix=/home/ler/pg-test --enable-syslog \
--with-CXX --with-perl --enable-multibyte --enable-cassert \
--with-openssl --with-tcl \
--with-tclconfig=/usr/local/lib/tcl8.3 \
--with-tkconfig=/usr/local/lib/tk8.3

I get the following death:
