problem upgrading from 5.0 to 5.1

[Paul Chvostek]

I'm confused...

I've got a box on which 5.0-RELEASE was installed.  I updated the source
tree using cvsup to RELENG_5_1 and tried to recompile, and now every
time it gets to bin/cat, it chokes.  The source tree *is* up to date,
I've tried running `make clean update buildworld` to no avail.  It
always stops in the same place.  I could do a proper reinstall from an
ISO, but I'd really like to know what's wrong.

Any idea what's happening, or where I should look?  I'm stumped.

Thanks.
