Log Message:
Update from version 0.21_03nb1 to 0.23, discussed with maintainer.

Pkgsrc changes:
 o Canonicalize HOMEPAGE
 o Fix MASTER_SITES to use MASTER_SITES_PERL_CPAN
 o Add patch to recognize lo0 on NetBSD.  This probably breaks the test
   on Linux.  It's not portable to insist on particular names for
   interfaces (lo or lo0), but this patch doesn't improve the portability,
   it just makes it pass on NetBSD.
 o Add patch to not do the mem_leak test if Proc::ProcessTable is installed
   but the platform does not provide the virtual size of the process via
   "size". (We probably should have a kvm-using version of \ 
Proc::ProcessTable,
   but that's for another day.)
