There was an attempt at that: cpan2port
[http://www.nabble.com/announce:-cpan2port-td20415884.html]. I don't
know what is its current status, but that's a nice thing. If it was also
possible to have this for python eggs, ruby gems, ctan, etc. However,
debian has had such a tool for a long time, other package managers also
have.

Concerning the possibility to search for which port I should install to
get which command, I usually try google with the name of the thing I
want to get and "debian". It usually gives me the name of the debian
package which is usually easily translatable into macports' naming.
Once more however, debian, pkgsrc and probably other ones provide a way
to search for the files provided by a package. In debian, as they make
binary packages, it is "simple". In pkgsrc, it relies on their build in
a sandbox which only uses the specified dependencies (not anything from
/usr/local or /usr if it is not explicitly said in the Makefile) and
hence builds exactly the same on machines with different things
installed.

Is macports bound to reinvent wheels over and over?
