Thank you for all the information :)
Also, my general advice for running anything from cron is always use absolute paths
Following this advice I have used the full path so my cron entry is:
*/2 * * * * /usr/bin/perl /home/pi/Curtains/curtains.pl
If I use /usr/bin/perl /home/pi/Curtains/curtains.pl from the command line then the script runs but it doesn't run from cron. So I have enabled logging in /etc/rsyslog.conf and I get this logged:
Dec 14 16:12:01 eric CRON[10129]: (pi) CMD (/usr/bin/perl /home/pi/Cur
+tains/curtains.pl)
Dec 14 16:12:01 eric CRON[10128]: (CRON) info (No MTA installed, disca
+rding output)
Dec 14 16:14:01 eric CRON[10135]: (pi) CMD (/usr/bin/perl /home/pi/Cur
+tains/curtains.pl)
Dec 14 16:14:01 eric CRON[10134]: (CRON) info (No MTA installed, disca
+rding output)
That explains why I am not getting any mail! But doesn't explain to me why the script is not running from cron. I have tried chmod 777 curtains.pl and chmod 755 curtains.pl.
What else should I be looking at to try and debug this problem>

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
