I think it's worth noting the missing

/opt/perl/lib/site_perl/5.8.0/i686-linux-64int-ld
[download]

directory in there.

This bit me when moving from perl 5.6.0 to perl 5.6.1 where as in your example perl 5.6.1 was only picking up the site_perl/5.6.0 directory but not the site_perl/5.6.0/i386 one.

Anyone know if this behaviour is intentional or just a consequence of the way perl happened to be compiled ? (I'm using standard Red Hat RPMs)
