Why not, what happened?

Why not, what happened?

Well, see, is the directory that contains the instructions for how to install all the ports; if you've deleted parts of that, then MacPorts won't know how to install those ports anymore. The directory isn't really meant for you to modify, since MacPorts will throw away your changes when you sync. So that's also the solution for how you get it back: just sync ("sudo port sync").

Uninstalling and reinstalling MacPorts is another option; sounds like that wouldn't be too inconvenient for you at this stage, if you decide to go that route. Uninstallation instructions are in the Guide. However, looking forward to the day when you do have lots of things installed with MacPorts and uninstalling completely would be an inconvenience, you may want to pursue the above less-destructive route, in order to familiarize yourself with how MacPorts works. In the event the above doesn't work, please show us what you typed and what error messages were returned.
