I got it from the error message above.  ;-)

This is a vanilla install using the ISO CD image downloaded yesterday
and installed, followed by a portsnap fetch and portsnap extract.
I haven't made any edits to /etc/make.conf or changed any other 
settings.  Expected it to work "out of the box" but for some reason it 
doesn't.

Am I correct in assuming that the 7447 came as a result of the kernel
reading the PVR at some point?  Or is this due to the gmp port's own
attempt to get the processor version in config.guess?  How can I confirm 
which of 7447 or 7450 is correct?
