10.6 MacPerl - no appropriate 64-bit architecture

Anyone else seeing issues with Snow Leopard /usr/bin/perl modules on  
64bit hardware?

This does not appear to be an issue if the /usr/bin/perl5.8.9 perl is  
used instead (yup - there are two perls installed on snowy!)

Sadly I'm a poor core-duo (32bit) user so I can't reproduce this - I'm  
just receiving bug reports...

Any insights?
