The pkg_delete(8) man page could be helpful.
If there is a decision involved, this might help direct a solution:
Code:
-i Switch on interactive mode. pkg_delete may ask questions
to the user if faced with difficult decisions.
If that fails, this should produce more detail about the problem:
Code:
-v Turn on verbose output. Several -v turn on more verbose
output. By default, pkg_delete is almost completely
silent, but it reacts to keyboard status requests (see
stty(1)). -v turns on basic messages, -vv adds relevant
system operations, -vvv shows most internal computations
apart from individual file/directory additions, and
-vvvvv shows everything.
