<p>Thinking further, the following can now be removed from <code>subst.in</code>:</p>

<pre><code># add to libexecdir to INC for perl utils.pm
/^use/ { if (/lib/) { if (/utils.pm|"."/ ) {sub(/utils.pm|"."/,led() )} } }
</code></pre>

<p>Removing this would stop new contributions from accidentally using it again.</p>

<p>The whole <code>led()</code> function could be then removed too.</p>
