I doubt my solution is generic enough for you, although it matches the data supplied and so might form a starting point. sub table() is included to make the output a bit more readable. 

use feature ":5.14";
use warnings FATAL => qw(all);
use strict;

sub table($;$$) # Table formatter
 {my ($d, $c, $w) = @_; # Data, control, width
  my @D;
  for   my $e(@$d)
   {for my $D(0..$#$e)
     {my $a = $D[$D] // $w->[$D] // 0;
      my $b = length($e->[$D]);
      $D[$D] = ($a > $b ? $a : $b);
     }
   }
  my @t;
  for   my $e(@$d)
   {my $t = ''; 
    for my $D(0..$#$e)
     {if (substr(($c//'').('L'x($D+1)), $D, 1) =~ /L/i)
       {$t .= substr($e->[$D].(' 'x$D[$D]), 0, $D[$D])."  ";
       }
      else  
       {$t .= substr((' 'x$D[$D]).$e->[$D], -$D[$D])."  ";
       } 
     }
    push @t, $t;
   }
  @t
 }

my @t = ([qw(name version release arch)]);

for(split /\n/, << 'END') # Parse sample data
fipscheck-1.2.0-1.el5.x86_64
iptables-ipv6-1.3.5-5.3.el5_4.1.x86_64
libXi-1.0.1-4.el5_4.i386
perl-Carp-Clan-5.3-1.2.1.noarch
rpm-build-4.6.1-2.el5.x86_64
END
 {my ($name) = (split /\./)[0] =~ s/..\Z//r;
  my ($version) = /-([\d\.]+)/;
  my ($release) = /.*-(.*)\./;
  my $arch = (split /\./)[-1];
  push @t, [$name, $version, $release, $arch];
 }

say for table([@t]); # Format data
