Using pkgsrc from Sep-01 on NetBSD 1.5W, I'm unable to delete some
packages installed from an earlier version of pkgsrc:

root@lintu x11/gnome # pkg_delete -f imlib-1.9.8.1
pkg_delete: file `/usr/X11R6/bin/imlib_config' doesn't really exist
Segmentation fault (core dumped)

in gdb:

pkg_delete: file `/usr/X11R6/bin/imlib_config' doesn't really exist
(no debugging symbols found)...(no debugging symbols found)...
Program received signal SIGSEGV, Segmentation fault.

I haven't seen this on other machines, so I guess something must be wrong
with the pkgsrc database (I said "I guess!" :) but I don't know how to
fix things - do I "rm -rf /usr/pkg /var/db/pkg" or...?
