title: Perl Script Portability and Future Proofing
body: <p>Due to pressure from outside our group, we have to port over one hundred Perl scripts from Sparc to x86. This means changing dozens of shebang lines from <code>#!/home/Perl/bin/perl -w</code> to something else, which is a real pain. What is good way to do this (I can't find anything on <a href="http://search.lycos.com/?tab=web&amp;query=Port+Perl+Scripts+from+Sparc+to+x86" rel="nofollow noreferrer">Lycos</a>)? </p>
  
  <p>Also what happens when we're forced to move from x86 to something else (like Cray, I suppose)? Is there some way to "future-proof"?</p>
