I wrote this pstack wrapper for gdb... you (and others) may find it useful:

#!/opt/perl/bin/perl -w
use strict;

die usage() unless(@ARGV);
die usage() unless($ARGV[0] =~ /^\d+$/);

my $gdb = "/opt/langtools/bin/gdb";

my $tmp = "/tmp/pstack.$$";

open(OUT, ">$tmp") || die "$!: $tmp";
print OUT<<EOF;
set pagination off
set width 65536
thread apply all bt
detach
EOF
close OUT;

system($gdb, "-pid=$ARGV[0]", "-batch", "-n", "-x", $tmp);

unlink $tmp || die "$!: $tmp";

sub usage {
   return "Usage: $0 <pid>\n";
}
