The tool to use for low-level package management is dpkg.  For example: 
'dpkg -r <packagename>' will remove a package.  The man page also 
describes other options to force removal even with dependency issues.

As for the libssl issues, I use debian, not Ubuntu, and I'm not sure how 
exactly they differ in repository management.  My guess would be one of:
	a) There's some sort of transition going on in the repository
	b) You're hooked up to multiple repositories hosting the same
		files with different versioning schemes

I'll let the Ubuntu guys on the list give you a better answer for that
