RHEL Linux x86_64
Had 64 bit perl installed
Installed the 32 bit libraries since ARS couldnt see the 64 bit shared
object i built.
Recompiled and linked using 32 bit libraries.
So i now have a 32 bit shared object.

I thought the above looked good since it all points to the 32 bit
libraries.

---------------------END PERL -V -----------------
The only thing i was wondering about - was even though i have both
x86_64 and i386 perl packages installed - and i successfully compiled
arfperl against the 32bit i386 version whether how ARS invokes perl
might have an impact - isnt it purely through the arfperl.so and its
dependencies - so if they are all 32 bit and existent we should be good.
