mutt on RH 7.1, continued

[Jonathan Q <jq@example.com>]

I copied a binary over from my RH 7.0 system at home 
(actually even older than that, I think I compiled it
on a TurboLinux 6 system, or maybe even 4.2, it 's 
mutt 1.0.1i-jp0 from 2000-01-18) and that does Japanese fine
on the RH 7.1 system.  

Is this an indicator of a borked iso-2022-jp, or am I
barking up the wrong tree on this?

Thanks,

Jonathan
