Problem with dependencies during installation

["MCDOUGALL,DAVID (HP-Roseville,ex1)" <david_mcdougall hp com>]

Hello All,
           I have created a package which contains some Shared Object files
and these are
listed under %files in my spec file. 

%files -n myPackage
...
%attr(550,bin,bin) /opt/myprog/lib/libMylib.so
%attr(550,bin,bin) /opt/myprog/lib/libMyOtherlib.so

My problem is that when I try to install the package
I get an error:-

error: failed dependencies:
          libMylib.so is needed by myPackage-01.00-1
          libMyOtherlib.so is needed by myPackage-01.00-1

Any help appreciated. I thought that rpm would add the shared objects in the
files list to
its dependency database, but this does not seem to be the case.

Cheers,
           David.
