Pay closer attention to where you are putting your brackets. Look at Charmy's example above. Also, you might want to try something like this to eliminate duplicate code (untested):

if ($text =~ /hail/i)
{
   if ($class eq "Rogue")
   {
      if ($ulevel > 64)
      {
         quest::say ("you're over 64!");
      }
      else
      {
         quest::say ("you're not over 64!");
      }
   }
   else
   {
      quest::say ("begone! you're not a rogue!");
   }
}

Also, if you do not know what is causing a problem with your perl, run it with perl, rather than through the emu!
