Are you using cpan to install apache?

Revision history for this message

No.

When I click on a link on the web page and a program is run that needs a
perl module like Date::Calc installed using cpanm, the module cannot be
found. I now see that the module is installed because when I try to
reinstall it, I am told it is up-to-date.

Here is a sample of the error message I get when I click a link on a
webpage.

*Can't locate Date/Calc.pm in @INC (you may need to install the
Date::Calc module) (@INC contains: /home/coacho/lib
/home/coacho/perl5/lib/perl/5.18 /home/coacho/perl5/lib/perl/5.18.2
/home/coacho/perl5/share/perl/5.18 /home/coacho/perl5/share/5.18.2

/usr/lib/x86_64-linux-gnu/perl-base) at ./lib/cvt_date2day.pl line 13.
BEGIN failed--compilation aborted at ./lib/cvt_date2day.pl line 13.
*

I have just noticed that the directory noted /home/coacho/perl5*, *is
the production directory and not the directory used in our lab.*
*

How do I tell apache2 where to look for the cpan modules?

Maybe this will help

In the error below the @INC includes this
/home/coacho/perl5/lib/perl/5.18
this is defined on our production server but the perl5 library should be
/home/bill/perl5 or our lab server

I do not know where the /home/coacho/perl5/lib/perl/5.18 is coming from.

Here is another piece of this puzzle.

When I login to the lab web server and run a Perl script from command
line, that I know will fail, the paths noted in INC in the error message
are correct. They show the local::lib values correctly.
