Well, the FreeBSD port does it this way (in the ports Makefile):
.if defined(USE_TCL)
TCL_INCDIR= ${LOCALBASE}/include/tcl8.0
TK_INCDIR= ${LOCALBASE}/include/tk8.0
MAKE_ENV= USE_TCL=true TCL_INCDIR=${TCL_INCDIR}
WITH_TCL= --with-tcl --with-tclconfig="${LOCALBASE}/lib/tcl8.0 \
${LOCALBASE}/lib/tk8.0"
.endif
...
CONFIGURE_ARGS= --prefix=${PREFIX}/pgsql \
--enable-locale \
--with-template=`uname -s | ${TR} '[A-Z]' '[a-z]'` \
--with-includes="${PREFIX}/include ${TCL_INCDIR} \
${TK_INCDIR}" ${WITH_TCL} \
--with-libraries=${PREFIX}/lib
which ends up to
$ ./configure ... --with-includes="/usr/local/include \
/usr/local/include/tcl8.0 \
/usr/local/include/tk8.0" \
--with-tcl --with-tclconfig="/usr/local/lib/tcl8.0 \
/usr/local/lib/tk8.0"
$ USE_TCL=true TCL_INCDIR=/usr/local/include/tc8.0 gmake
Hope this helps. Check the complete FreeBSD port at
