make index strangeness after today's cvsup of ports tree

[Stacey Roberts]

Hello,
     After today's cvsup'd ports tree (and portupgrade of gnome-2 to
latest in ports), make index returns some weird messages.

Here is the tail of it:
cd: can't cd to /devel/libgnugetopt
cd: can't cd to /devel/libgnugetopt
cd: can't cd to /devel/libgnugetopt
cd: can't cd to /devel/libgnugetopt

cd: can't cd to /devel/libgnugetopt

2>/dev/null | /usr/bin/sed -e 's/.*: //'" returned non-zero status
 Done.

Does anyone know what these messages mean?

Regards,

Stacey
