Oooooops: make deinstall

[Tom Vilot]

I inadvertently invoked make deinstall from /usr/ports, thinking I was 
in the directory of the port I wanted to 'make deinstall && make reinstall'

I wasn't.

Oops.

I'm in the process of re-installing those ports I installed and depend 
on (firefox, thunderbird, etc).

But ... since I control-c'ed the ill-chosen 'make deinstall', I'm sure I 
have left my package database in a rather un-tidy state.

Is there an easy way to say, either with portupgrade or make or any 
other tool, the equivalent of:

"what ports are installed? Are they *really* installed?
 What do they depend on? Are those installed? Are they *really* installed?"

Of course I can do portupgrade -l "<" -O, but I think my question is: 
does that tell me if my system is actually clean?

:c)

Also --- is there some way of looking at an "audit trail" or some way 
that I can see what ports/packages I had previously installed before I 
accidentally did make deinstall?

Thanks ...
