install the library by hand to the standard location or set LD_LIBRARY_PATH
in your debian.rules file.

There are two points:
all libraries not supplied by your package you should (temporarily, until
they're fixed) put into shlibs.local with their full dependency.
for your own lib there are two cases:
- you have a single package containing the library and some programs using it.
it would be a mess if dpkg-shlibdeps generates a dependency of the package
to itself. use a line
libwhatever fullversion
in youre shlibs.local so dpkg-shlibdeps finds the library but generates
an empty dependency.
- you have one package containing the library and a different package
containing programs using this library. The best way, IMHO, is to
generate the library package first, install it and rebuild all packages
after that. As you installed a shlibs control file with the shared lib
package, dpkg.shlibdeps will work fine.
And don't forget, you have to install a shlibs control file in every package
containing a shared library but those in /etc/dpkg/shlibs.default.
