While updating pkg's I've encountered a problem:

--8<--
[/usr/pkgsrc/graphics/Mesa-glx] root@rumolt > make update
===> Resuming update for Mesa-glx-tnt-19990804
===> Installing for Mesa-glx-tnt-19990804
===> Mesa-glx-tnt-19990804 conflicts with installed package(s): Mesa-glx-tnt-19990804  found.
*** They install the same files into the same place.
*** Please remove Mesa-glx-tnt-19990804  first with pkg_delete(1).
*** Error code 1

Is this to be expected? I realy do want to rebuild that package, no matter if
the pkg system thinks something changed.
