Upgrading between major versions requires all installed ports to be
rebuilt, so they get linked to the new versions of the libraries.
I suppose you missed this step, older apps may still work but there is a
problem installing new ones.

Please see the instructions at the end of section 24.2.3 (portupgrade etc):


These are still applicable even if you used the traditional source-based
way of upgrading the base system (instead of freebsd-update)

(AFAIR,  if you upgraded via source, you will also need to run make
delete-old-libs in /usr/src after successfully recompiling ports)
