MacPorts seems to be working, so I don't see any need to uninstall or reinstall
MacPorts.
It sounds like some or all of the files that were supposed to have been
installed by some of the ports you have installed are missing. I'm not sure how
that situation arose. But the usual way to get back files that a port installed
that have mysteriously vanished is to deactivate and reactivate the port. Since
it sounds like you have multiple ports affected by this problem and don't know
exactly which ones, you could deactivate all of your currently-active ports and
then reactivate them.
To get a list of all the currently active ports and their versions and
variants, you could run:
port -q installed active | sed 's/ (active)$//' > activeports.txt
To deactivate those ports, you could run:
xargs sudo port deactivate < activeports.txt
To reactivate those ports, you could run:
xargs sudo port activate < activeports.txt
You should then have all the same ports active as before, but any files that
those ports were supposed to have installed that went missing should now be
present again.
You can then delete activeports.txt.
