Let's say there are two ports A & B.
They both provide libfoo.so.1 (and so register CONFLICTS with each other).
Now port C wants to use libfoo (and doesn't care if it gets it
from A or B).
What does port C list in it's LIB_DEPENDS?
Whichever one the author of port C chooses.
Quite often, at least for things like the BerkeleyDB, the author of port C
will provide tunable OPTIONS or WITH_ or WITHOUT_ flags that you as the user
of the port can tune to choose a particular version that you like.
What if it lists A and someone installs B... does A get registered as
the dependency when C is installed even though A is not installed?
No, the port should be registered against B and not A, if B is installed.
However, if a porter misses listing a necessary dependency, then things can
get a little confused, and running "pkgdb -F" might help...
