Ah, well, yes, you're right of course, I didn't mean that users should use obscure commands; I meant the information is already available via those commands, so we needn't go through thousands of portfiles adding this information and keeping it updated there forevermore, when it's redundant. Certainly MacPorts could be enhanced with a command (port distsize?) that would print the filesizes for you. Or the web site could be enhanced to include that information.

We might have to forgo this for ports that don't fetch distfiles (fetch.type cvs, svn, git, hg, ...)

Certainly a proper progress bar for downloads in MacPorts would be nice. Currently we just let curl print whatever it wants, but when we have ports like gcc4* that download five large distfiles, it's nice to know the overall progress, not just the progress of each file. But that is the exception; most ports just have one distfile.
