I've come across some unexpected behaviour that I thought was obvious but it seems not so your input would be welcome...

On a webserver I have a maintenance script that runs off CRON every morning. The filesystem looks like this: 

/home/username/website/prod/lib       <- modules
/home/username/website/prod/template  <- templates
/home/username/website/prod/www       <- HTTP root

[download]
There is also a test environment as well as prod
To set @INC correctly, this line is at the top of every script that needs to run in CGI context 
use lib "$ENV{'DOCUMENT_ROOT'}/../lib";

[download]
But, when run by CRON, the maintenance script doesn't get passed $ENV{'DOCUMENT_ROOT'}.

However, the maintenance script is located at: 

/home/username/website/prod/lib/maintain.pl

[download]
It needs to 
use Site::Utils;

[download]
where the module is located at 
/home/username/website/prod/lib/Site/Utils.pm

[download]

I thought I could simply use lib "."; to add the current directory to @INC or even leave it out altogether and Perl would find the module by searching the filepath relative to the running script.

But both these approaches result in Perl reporting that it cannot find the module...

What am I overlooking here?
