After upgrading to Perl 5.10 on an Ubuntu Linux box, I went to use a script which, deep inside LWP::UserAgent, uses Crypt::SSLeay. This script worked flawlessly for > 1 year on 5.8. But on 5.10 I got this message. 

Crypt::SSLeay not installed:

/usr/local/bin/myscript.pl (via LWP) will support https URLs if the Cr
+ypt::SSLeay module is installed.

I then tried to use the cpan shell to install Crypt::SSLeay. I got this message: 

This host looks like it is running Debian. Crypt::SSLeay needs to be c
+ompiled with C headers that the libssl-dev package makes available. P
+lease install that package before trying to build this module. (You c
+an always deinstall the package afterwards, once Crypt::SSLeay has be
+en built).
Which SSL install path do you want to use?

Finally, when I went to (re-)install libssl-dev, I got the following message through both apt-get and the Synaptic Package Manager: 

[~] 503 $ sudo apt-get install libssl-dev
Reading package lists... Done
Building dependency tree... Done
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 tha
+t
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:

The following packages have unmet dependencies:
  libssl-dev: Depends: zlib1g-dev but it is not going to be installed
E: Broken packages

Suggestions as to how to proceed? Thanks in advance.
