can no longer "make index" when merging marcuscom ports

[Scott I. Remick]

Sometime in the past few days, I've stopped being able to run a "make
index" after merging the marcuscom ports module w/ a freshly cvsup'd ports
tree. It had worked for me before post-Gnome 2.12's inclusion but now I
get the following error. If I cvsup ports without running marcusmerge, I
can "make index" just fine. I am on FreeBSD 5.4-RELEASE-p1 

Generating INDEX-5 - please wait.."/usr/ports/Mk/bsd.gnome.mk", line 585: warning:

********************************************************************
Before reporting this error, verify that you are running a supported
version of FreeBSD (see http://www.FreeBSD.org/ports/) and that you
have a complete and up-to-date ports collection.  (INDEX builds are
not supported with partial or out-of-date ports collections -- in
particular, if you are using cvsup, you must cvsup the "ports-all"
collection, and have no "refuse" files.)  If that is the case, then
report the failure to ports at FreeBSD.org together with relevant
details of your ports configuration (including FreeBSD version,
your architecture, your environment, and your /etc/make.conf
settings, especially compiler flags and WITH/WITHOUT settings).

Note: the latest pre-generated version of INDEX may be fetched
automatically with "make fetchindex".
