Horology & stats tests fail in 7.4.3/RH 9

I am building from a freshly downloaded tar.gz of 7.4.3. The machine is
a 4CPU Dell with an unsupported RH 9 install. (FWIW, I didn't set it
up, and to do anything requiring root access I have to go sit at the
IT guy's console from which he SSHs in to the box. The IT folks are
smart but not Linux cogniscenti.)

When I ran the regression tests, two failed: horology and stats. I'll
append the content of the regression.diffs file to the posting.

Is this something I should be worried about? I can get more info about
the system if that would be helpful, but the only configure option I
exercised was '--prefix=', so I'm not sure what would be helpful.

Thanks in advance,
Chuck
