[Ivaylo Bonev]

Hi, I want to update ports and when I try I see this error
# portversion -l '<'
freetype2                   <
ghostscript-gpl             <
# portupgrade -arR
** Makefile possibly broken: print/ghostscript-gpl:
        "Makefile", line 132: warning: drivers incompatible with WITHOUT_X11
will be removed automatically
        ghostscript-gpl-8.62_3

I use FreeBSD 7 with up to date ports without X11. I don't have anything in
make.conf except Perl lines.
How can I update these ports?
CC to me please.
