libxmu-dev is not the only one missing, also libxaw6-dev:
=====
Finished compiling gcl_dwtrans.lsp.
("gcl_Xlib" "gcl_Xutil" "gcl_X" "gcl_XAtom" "gcl_defentry-events"
 "gcl_Xstruct" "gcl_XStruct-l-3" "gcl_general" "gcl_keysymdef"
 "gcl_X10" "gcl_Xinit" "gcl_dwtrans")

>/usr/bin/ld: cannot find -lXaw6
collect2: ld returned 1 exit status
sh: ./raw_saved_xgcl: No such file or directory

However, adding libxmu-dev and libxaw6-dev is still not enough:
=====

make[3]: Leaving directory `/tmp/buildd/gcl-2.6.7/info'
if test "/usr/share/info/" != "unknown"; then (cd xgcl-2 ;
/usr/bin/make install DESTDIR=/tmp/buildd/gcl-2.6.7/debian/gprof) ; fi

Now, the problem is that latex2html is in non-free, so adding a
dependency on it renders gcl suitable for contrib.  However, the
gcl-doc package includes the HTML documentation generated with
latex2html as well as the original TeX file and the PDF version
(generated from the TeX file through pdflatex/tetex-bin, already in
the dependencies).  This means that the gcl-doc package is already
built with latex2thml :-(

This is the reason the patch included adds not only the missing
dependencies, but also a new one on dpatch.  It thus includes a patch
which modifies the xgcl-2/makefile:all target to build only the PDF
documentation.  The patch has been prepared as an NMU and tested on a
just-update sid pbuilder, because I'm passing the T&S step as a new
maintainer.  The command used is the following:

debdiff gcl_2.6.7-15.dsc /var/cache/pbuilder/result/gcl_2.6.7-15.1.dsc

BTW, I'm aware that Debian prefers HTML documentation, but I won't
move a package to contrib only because the documentation can't be
available as HTML, when it can be as PDF.  A note can be added to the
README.Debian, in order to instruct the user how to generate the HTML
documentation form the original TeX file (which is anyway provided).
In this case, I'll suggests latex2html.

Thx, bye,
Gismo / Luca
