It should be fine to delete the corrupted package, delete the
package's directory in "/var/db/pkg" if necessary, do a "pkg_admin
rebuild", then re-install. If "pkg_admin check" ever finds errors, by
the way, it's a good idea to delete the suspect package before running
"pkg_admin rebuild", otherwise you're just papering over the errors,
defaeating the whole purpose of the checks.

I did write a utility (pkgdb), as part of a larger project, that can
add or delete individual keys:
It uses pkg_add's libinstall to do the dirty work, so it can't do
anything too weird or incompatible with the pkg_tools.
