Sadly not, but my Ports tree is not up to date, so I tried to compile
it in PORTVERSION=4.82A, with this error:

After I updated my Ports (just right now) I saw that lsof didn't change,
still same version number.




Installation via pkg_add -r worked without problems.

# pkg_add -r lsof

I've got lsof-4.82A,3 now. The manpage reveals that this seems to be
exactly what I've been searching for, so "lsof | grep usr" should to
the trick. Thanks!
