> Dear PARers,

> First of all, to be able to compile PAR on Tru64 we had to change the

> /usr/lib/perl-5.8.0/lib/5.8.0/alpha-dec_osf/CORE'.
> 
> We are then able to compile PAR, perform 'make' and 'make install',

                "Unaligned access pid=225910 <static> va=0x11fffbbac
pc=0x1201a4140 ra=0x1201a5614 inst=0xa4200000"

The background of these messages is briefly explained at
http://wwwrsphysse.anu.edu.au/doc/freeware/faqs/programming.html,
Question 7. More info can be found in the uac manpage and the Tru64
Programmer's Guide.

        As one of you guys please have a look at this. That would be
great!
