We should keep the discussion on the mailing list.

That would answer the present question "what port provides this executable
program in ${prefix}/bin" but what about ports like apache2 that install their
binaries elsewhere? What about GUI programs? What about manpages or perl
modules or php modules etc. that people sometimes ask about?
You talk of keeping a database of files, populated by the buildbot, I presume.
What about ports the buildbot cannot build? What about differences in installed
files based on variant or platform? Where would the database live -- on the
server only, or copied to each user's computer? If on the server only, how does
MacPorts query it? If on each user's computer, how is it synced?
I also don't know how to change bash's behavior when a command is not found,
but I guess that capability exists. How would we make this change for users?
Currently the user's .profile is modified only by the installer package
postflight script; how would users who selfupdate get this change? Do we take
this opportunity to get away from inserting our code directly into .profile and
switch to inserting just a command to source a script of our own, which I
believe we already have in the repository but are not using yet?
