Ports Collection - INDEX Error (FreeBSD 5.4)

[Benjamin Keating]

I did a very generic install of FreeBSD 5.4 on stable hardware.
Updated ports and then did this:

toki# cd /usr/ports/
toki# make index
Generating INDEX-5 - please wait.."/usr/ports/Mk/bsd.port.mk", line
4847: warning: duplicate script for target "add-p
list-post" ignored
fityk-0.4.4_1: "/usr/ports/x11-toolkits/wxgtk2" non-existent --
dependency list incomplete
===> math/fityk failed
*** Error code 1

1 error

********************************************************************
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not supported with partial or out-of-date ports collections -- in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".

Stop in /usr/ports.

Stop in /usr/ports.

This has happend to me before. How can I prevent this from happening?
I'd like to automate cvsup / index building.

thx
