I don't know how this works for you but I have the following so that I
can build the libraries I want as modules:

  # Backend Language Writer
  include $(top_srcdir)/Makefile.include

  modules_LTLIBRARIES =

Automake handles all the duties of building the modules. Libtool is used
to build a module with the flags (set in, exported as a
Makefile symbol and incorporated into the <module_name>_LDFLAGS:

  MODULE_LDFLAGS="-export-dynamic -module -avoid-version"

So now all I got at this point was a .so and a .la file. Both were
installed. So now that leads us to your solution.

I know that you are trying to clear out all the directories on
installation. I found that automake wanted to use pkglibdir instead. So
as you can see above I incorporated that into setting the destination
directory. So I find this unnecessary.

Automake handled installation of the files find. So I am not going to 
try and break something that works. I get both .la and .so installed but
I changed your idea to do:

        @list='$(modules_LTLIBRARIES)'; for p in $$list; do \
                rm -f $(modulesdir)/$$p ; \

modules_LTLIBRAIRES has a list of .la files. The very thing we do not
want permanently installed. So all I do is remove after the installation
is complete.

This was unnecessary since automake did a good job of removing both the
.so and .la files when they were installed. So I did not feel this was

See my above comment about pkglibdir.

Thanks for the ideas Tom. I got want I wanted in the end. You helped me
remember the -avoid-version flag.
