[Dune] Creating new modules

[Oliver Sander]

Hi Bernd!
What you describe is a known deficiency of the Dune buildsystem.
In fact it is entry 230 in our bugtracker.

If you just want headers from your Mod1 the quickest way is
to add an extra -I to the CPP_FLAGS in the Makefile.am of
Mod2 and thus hardcode the path of Mod1 there (not nice,
but easy).  If you want to link to Mod1 or if you just want to
to it right you have to modify dune.m4 and dunecontrol.
That is pretty straightforward.  However in order to not
screw up your build system you have to do that with the
svn version instead of the tarballs because you need to
call autogen.sh before being able to configure.

I hope this helps.  I'll set up the bug's priority as this really
is important.
