Hi I have a perl script that runs OK from the terminal but won't run from cron. I get a logged error that looks like this: 
May 24 09:00:02 trackcam3 test_cron: Can't locate Image/Grab.pm in @IN
+C (you may need to install the Image::Grab module) (@INC contains: /e

So I ran: 
darren@trackcam3:~ $ cpan Image::Grab
Loading internal null logger. Install Log::Log4perl for logging messag

Image::Grab is up to date (1.4.2).

This looks like cron doesn't have the right path in the environment
The path statement in crontab looks like: 
  PATH=/home/darren/perl5/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin
+:/usr/bin:/sbin:/bin
# PATH =/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

The uncommented path is the same as the one in my user profile. The commented path is the one that has worked for years.
This problem started when I build a new server from scratch using a documented procedure. Something I have done quite a few times. Something new has happened during the build. I don't know what that was and I don't know how to solve this problem.
