Hi Arjen:
I decided to have a look at this because like Andrew and you I have several
versions of tcl available (in my case tcl8.3 and tcl8.4 for Debian Lenny).
As root I used
update-alternatives --config tclsh
to select tclsh8.3.
However, it turns out I cannot even generate the tcl bindings source code
with tclsh8.3! Here is the relevant trailing part of the output of "make
VERBOSE=1".

When I use update-alternatives to select tclsh8.4 the above issue disappears,
everything builds with "make" or "make all", and all tests run successfully
with "make test_noninteractive".
I double-checked with ldd that tclsh8.3 was properly linked to
libtcl8.3.so.1 on my system.
Also, I checked on the command line that
/usr/bin/tclsh8.3 \
/home/software/plplot\ svn/HEAD/plplot_cmake_qt/bindings/tcl/pltclgen.tcl \
/home/software/plplot\ svn/HEAD/plplot_cmake_qt/bindings/tcl
generated the above error messages while
/usr/bin/tclsh8.4 \
/home/software/plplot\ svn/HEAD/plplot_cmake_qt/bindings/tcl/pltclgen.tcl \
/home/software/plplot\ svn/HEAD/plplot_cmake_qt/bindings/tcl
worked fine. The above issue cannot have anything to do with incompatible
library versions since all it does is process some input to create some
output. Thus, I think pltclgen.tcl must have some code in it that depends
on the tclsh version being 8.4 or higher.
Arjen, it sounds like you are pretty busy at the moment, but will you put
this issue on your ToDo list for PLplot? If you can confirm this issue in
your pltclgen.tcl script with tclsh8.3, then I think it is important that
you fix it. Geoffrey has made the point a number of times that the so-called
"enterprise" versions of Linux have really old versions of software packages
in them. Thus, I think it is likely that some of our potential Tcl users
will still be using Tcl8.3 and will quietly ignore PLplot because of the
above issue.
Meanwhile, the above issue keeps my from participating in tests about
whether tclsh can have an inconsistent version with the libraries (say
tclsh8.4 versus Tcl8.5 libraries). I have grepped through our build system
for where tclsh is invoked, and it is almost entirely used to generate stuff
(such as the code for the tcl bindings as above) rather than to run
examples. Thus, my current guess is for teclsh8.4 (or higher) and some
incompatible Tcl library version, "make test_noninteractive" and "make
"test_interactive" would work fine.
I did find one instance of a test recommended in
examples/tcl/README.tcldemos that uses tclsh. My guess is incompatible
versions of tclsh and the Tcl libraries would wreak havoc on that particular
test. However, to check that you will have to run that particular test from
the command line because I haven't yet (although I hope to do so in future)
included it in the test_noninteractive and/or test_interactive targets.
