Besides the "Suggested resolutions" I mentioned in my previous posting,
you might be missing the fact that if you identify/guess full pathnames
for the libraries, then you can obtain the package names with "-qf".

For example:

rpm --dbpath /usr/lib/rpmdb/i386-redhat-linux/CentOS -qR httpd

prints a long list of CentOS httpd's dependencies, including:

libgssapi_krb5.so.2

If you guess that this library likely installs under /usr/lib, like most
of them do, you can query:

rpm --dbpath /usr/lib/rpmdb/i386-redhat-linux/CentOS -qf /usr/lib/libgssapi_krb5.so.2

which prints:

krb5-libs-1.3.4-62.el4

All of the above works with just rpmdb-CentOS installed on Owl, with no
other CentOS packages downloaded/installed yet.

The "Suggested resolutions" on attempted install are even easier to use.
