	If the OP's intention is to be able to reconstruct the dependency tree, 
he's hosed.
	If the intention is to find out what was installed, there is some hope. 
  This method works under the following conditions:

	1) you were using ports (it may or may not work for packages)
	2) you have not deleted /usr/ports/distfiles

	Basically, sweep through /usr/ports/distfiles.  Most entries can be 
pretty easily mapped to the associated port, including version number.
	Unfortunately, I know of no way of rebuilding the contents of 
/var/db/pkg without re-(compiling, installing) every component of every 
port.  If it does not exist, this would be a _killer_ ability to have; 
it's not often required (one hopes!) but when it is it would be a total 
lifesaver.
