Corrupt Ports - arts and jackit

[Jeff Cross]

When updating my system I keep getting the following message:

pkg_info: the package info for package 'arts-1.5.1_1,1' is corrupt
pkg_info: the package info for package 'jackit-0.100.0_2' is corrupt

I have tried uninstalling these ports (probably a bad thing) and
reinstalling them but when I try to install arts (alphabetical order
seemed logical enough to me) I get the following:

      You may wish to ``make deinstall'' and install this port again
      by ``make reinstall'' to upgrade it properly.
      If you really wish to overwrite the old port of audio/jack
      without deleting it first, set the variable "FORCE_PKG_REGISTER"
      in your environment or the "make install" command line.
*** Error code 1

Stop in /usr/ports/audio/jack.
*** Error code 1

Stop in /usr/ports/audio/arts.

Is there a way I can clean these two up?  How can I determine what
applications require these two?  I am assuming that now they are
uninstalled the ports requiring them will fail.  Am I right?

Thanks in advance.
