For a port with a large dependency tree and a slow computer, it could take some time to compute the dependencies.

I count 198 dependencies for texlive +full (or rather, "port rdeps texlive +full" does); at 40 minutes, that would be about 5 ports processed per minute, or about 12 seconds per port. That seems excessive... what is this computer's processor speed? how's the hard drive speed for other tasks -- does it seem to take a long time to access things?

On my 2.2-GHz MacBook Pro, it took only about 15 seconds to go from "Computing dependencies for texlive" to "Dependencies to be installed" and "Fetching" the first needed dependency. Granted I do already have many of the dependencies installed, but the time to compute the dependencies should still be comparable.
