This is a bug in the ports framework. It wrongfully assumes, that an
installed binary X is/was provided by port Y if you specify X:Y.
What it _should_ do is check for binary X, if present use pkg_info -W to
get the right port. If not present, use Y as a default port to pull in
this binary.
The same thing happens, if you e.g. install lynx-ssl and some other port
depends on lynx (the binary!) then a dependancy on lynx (the port) will
be recorded, not on lynx-ssl.
It is trivial to fix, iff you assume that the user only installs
software via ports and all the databases are consistent.
