5.1 upgrade from 5.0

[Chris Neustrup]

I have just upgraded my Thinkpad from 5.0 to 5.1.  It all seems to be 
working OK.  I have tried to get a new X server running and discovered 
that the ports collection is now different.  I tried to do a make on an 
X server, and it failed with an error message about COMMENTFILE being 
deprecated.  I then tried several other ports in astro, and some 
others.  They all fail in the same way:

===> SETIsupport
There is a COMMENTFILE in this port.
COMMENTFILEs have been deprecated in
favor of COMMENT variables.
Please, rectify this.
*** Error code 1

Stop.
*** Error code 1

Stop in /usr/ports/astro.


Woe is me.  What can I do?

Thanks in advance, Chris
