Sorry if I was unclear. I didn't call clisp-link directly but tried

   configure --with-module=gir --with-module=gtk+3 --cbc build.gtk+3

Iow. I didn't look at clisp-link at all but copied&modified files from 
the modules included with CLISP.

Nothing is wrong with the above REQUIRE form itself, but with the way 
clisp-link is used in the overall Makefile (in the 'full' target): It 
first tries to compile all requested modules before creating dynmod 
entries. The above REQUIRE form above is executed when compiling module 
gtk+3, but the gir module load file (dynmod/gir.lisp) is not yet 
available at this point.

I was able to compile the modules one after the other with
   configure --with-module=gir --cbc build.gtk+3
   cd build.gtk+3
   make MODULES='gir gtk+3'
Strangely, omitting module gir from the initial build does not work - 
probably the same effect as above.

Btw, module gir does not use a C component (anymore), which means that a 
current CLISP (newer than 2010-09-14) is needed to build it.

Apart from that, I do have some things working already.
If anyone wants to take a look or try it, I've uploaded the modules here:
   https://bitbucket.org/mak08/clisp-gir
(examples included) but beware that it's still under development.
Any kind of feedback is welcome of course.

I have the following remarks:

- The example at http://www.clisp.org/impnotes.html#mod-set-example
   has the argument to clisp-link in the wrong order:
     4. $ -link add linux base base+linux
   should be
     4. $ -link add base base+linux linux

- clisp-link handles absolute directories incorrectly:
    ./clisp-link add base base+gir /modules/configured/gir
    produces dynmod/gir.lisp
    (ext:appease-cerrors ; for DEF-CALL-OUT to non-existent functions
      (cl:load (cl:merge-pathnames 
"..//modules/configured/gir/ffigen.fas" cl:*load-truename*)))
    => note the "../" is wrong here.

- clisp-link add <source> <target> <module>
   exits with error if <target> exists. It would be nice if at least
   clisp-link add <target> <target> <module> was allowed.
