A package depends on a library built from the same source... how?

["Marcelo E. Magallon" <mmagallo@efis.ucr.ac.cr>]

Hi,

        I've been bitten by this multiple times, and everytime I think
 I've got it right, I find myself fixing it again.  Package foo and
 package libbar2 both come from source package foo.  foo depends on
 libbar2... how do I get it right the first time?  Is there any
 example _known_ to work.  Basically the problem I have is with the
 shlibs.local file, it looks like it's not read at all.  It reads:

     libbar 2 libbar2

 I use:

   LD_LIBRARY_PATH=`pwd`/debian/tmp/libbar2/usr/lib dpkg-shlibdeps

 but I can't get it to pick the right dependency of foo on libbar2
 unless I install libbar2...

 TIA,


                                                Marcelo
