Here is a simple Makefile snippet:
# Use lang/tcl83 by default...
WITH_TCL_VER?= 83
LIB_DEPENDS+= tcl${WITH_TCL_VER}:${PORTSDIR}/lang/tcl${WITH_TCL_VER}
...a more complicated version might be something like:
# Use TCL 83 by default, but look for and use other versions if present.
.if exists(${LOCALBASE}/lib/libtcl80.a)
WITH_TCL_VER= 80
.elif exists(${LOCALBASE}/lib/libtcl81.a)
WITH_TCL_VER= 81
.elif exists(${LOCALBASE}/lib/libtcl82.a)
WITH_TCL_VER= 82
.elif exists(${LOCALBASE}/lib/libtcl83.a)
WITH_TCL_VER= 83
.elif exists(${LOCALBASE}/lib/libtcl84.a)
WITH_TCL_VER= 84
.else
WITH_TCL_VER= 83
.endif
.if ${WITH_TCL_VER} == 80
LIB_DEPENDS+= tcl80:${PORTSDIR}/lang/tcl80
.elif ${WITH_TCL_VER} == 81
LIB_DEPENDS+= tcl81:${PORTSDIR}/lang/tcl81
.elif ${WITH_TCL_VER} == 82
LIB_DEPENDS+= tcl82:${PORTSDIR}/lang/tcl82
.elif ${WITH_TCL_VER} == 83
LIB_DEPENDS+= tcl83:${PORTSDIR}/lang/tcl83
.elif ${WITH_TCL_VER} == 84
LIB_DEPENDS+= tcl84:${PORTSDIR}/lang/tcl84
.else
.error WITH_TCL_VER must be one of 80, 81, 82, 83, or 84
.endif
