newbie ports question

[makisupa]

I seem to be getting myself in trouble repeatedly...I'm sure someone can
help...

Fresh install of 6.0 RC1, gnome 2.12 from marcus's tb, freshly cvsupped
ports.  I need to install some little apps like gaim and pan.  when
running 'make install clean' for these ports i'll get a message that the
correct version of port X is not installed.  Problem is make says i need
a newer version but the version numbers indicate i've got a newer
version than what its looking for.  Then a little part about
'FORCE_PACKAGE_REGISTER.'  There is an example of this below this
message.  If i use this it will install the older version of the
dependencies or at least register them.  I say this on the last system
that i hosed...2 copies of the same package would be registered.  Not
good. How should i *properly* install these ports?  As in what's not
going to get me in trouble?

      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 devel/glib20
      without deleting it first, set the variable "FORCE_PKG_REGISTER"
      in your environment or the "make install" command line.

Thanks for the help.  Loving my BSD laptop so far...just straightening
some things out.
