strange apt-get problem

["Jaldhar H. Vyas" <jaldhar@debian.org>]

I've made potato versions of my webmin packages available at an aptable
archive.  One of those, webmin-ssl has a depends line like this:

Depends: perl, debconf,libnet-ssleay-perl,libauthen-pam-perl

I'm getting reports when people do an apt-get install webmin-ssl, they get
the following error message.  Even though they have debconf, and
libnet-ssleay-perl installed:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

Sorry, but the following packages have unmet dependencies:
  webmin-ssl: Depends: debconf
              Depends: libnet-ssleay-perl but it is not going to be installed
E: Sorry, broken packages

Q1:  Why is apt-get refusing to install libnet-ssleay-perl?

Q2:  Even after manually install the dependencies, why does apt-get refuse
to install webmin-ssl?

Any insights welcome.
