Hi Glynn,

I tried the updated configure and ran into a few troubles:

My new system is Redhad 7.1 with tcl/tk 8.3 present. However, configure
doesn't detect it:

ls /usr/include/tk.h
 /usr/include/tk.h
ls /usr/include/tcl.h
 /usr/include/tcl.h
(version 8.3)

The libs are also there:
ls /usr/lib/libtcl
 libtcl8.3.so     libtclstub8.3.a  libtclx8.2.so
 libtcl.so        libtclx8.2.a     libtclx.so
ls /usr/lib/libtk
 libtk8.3.so     libtkstub8.3.a  libtkx8.2.so
 libtk.so        libtkx8.2.a     libtkx.so

If running simply
 configure
on the same machine:
checking for location of Tcl/Tk libraries...
checking for Tcl_Init in -ltcl... yes
checking for Tk_MainWindow in -ltk... no
checking for Tk_MainWindow in -ltk8.3... no
checking for Tk_MainWindow in -ltk... (cached) no
checking for Tk_MainWindow in -ltk8.3... (cached) no
checking for Tk_MainWindow in -ltk... (cached) no
checking for Tk_MainWindow in -ltk8.3... (cached) no
configure: warning: *** Unable to locate Tk library.

If running 
configure --with-tcltk-includes=/usr/include

checking for location of Tcl/Tk includes... /usr/include
configure: warning: *** Tcl/Tk includes directory /usr/include does not
exist.
checking for tcl.h... yes
checking for tk.h... yes
checking for location of Tcl/Tk libraries...

 -> huh?

-> the head file doesn't contain entries for TCLINCDIR, TKINCDIR and
TCLTKLIBPATH.

Generally I think the 5.0.0 should be released these days, but
above (new) bug should be fixed as 5.1 won't be available for some
time.

Testing on SUN I get:
checking for location of Tcl/Tk includes... /usr/local/include
configure: warning: *** Tcl/Tk includes directory /usr/local/include does
not exist.
checking for tcl.h... yes
checking for tk.h... yes
checking for location of Tcl/Tk libraries... /usr/lib
checking for Tcl_Init in -ltcl... no
checking for Tcl_Init in -ltcl8.0... yes
checking for Tk_MainWindow in -ltk... no
checking for Tk_MainWindow in -ltk8.0... yes

Looks better but not perfect as the SUN head file finally contains:
#tcl/tk stuff
TCLINCDIR           =
TKINCDIR            =
TCLTKLIBPATH        = -L/usr/lib
TCLTKLIBS           = -ltcl8.0 -ltk8.0

Any help is welcome,

 Markus
