This breaks in the case depicted by ikegami, but can be adjusted to cope with the portability problem: 
#!/usr/bin/perl

use strict;
use warnings;
use File::Spec;

my $somepath = "/var/log/../../home/poletti/../../etc/rc.d";

my @true;
$somepath = "/../../../";
# Let's pretend $somepath is a directory... or is it? :)
/^\.\./ ? pop( @true ) : push( @true, $_ )
  foreach( File::Spec->splitdir($somepath) );
print File::Spec->catdir(@true), "\n";

Don't fool yourself.
