segmentation fault

[Steel City Phantom]

i am trying to run a portupgrade and have a problem.  portupgrade says i 
have a stale dependency and need to fix it with pkgdb, when i run that, 
i get this

guinness# pkgdb -F
--->  Checking the package registry database
Stale dependency: php4-4.3.5_7 -> apache-1.3.29_3 (www/apache13):
[Failed `Inappropriate file type or format'] [Updating the portsdb 
<format:bdb1_btree> in /usr/ports ... - 11973 port entries found 
.........1000.........2000.........3000.........4000.........5000......../usr/local/lib/ruby/site_ruby/1.8/portsdb.rb:587: 
[BUG] Segmentation fault
ruby 1.8.2 (2004-07-29) [i386-freebsd4]

i rebuilt the ports index by going to /usr/ports and doing make index, 
but i still get this same deal.

whats up?
