When I try to execute a perl script, I'm getting the following error:

Can't locate Date/Calc.pm in @INC (@INC contains: /usr/perl5/5.6.1/lib/sun4-solaris-64int /usr/perl5/5.6.1/lib /usr/perl5/site_perl/5.6.1/sun4-solaris-64int /usr/perl5/site_perl/5.6.1 /usr/perl5/site_perl /usr/perl5/vendor_perl/5.6.1/sun4-solaris-64int /usr/perl5/vendor_perl/5.6.1 /usr/perl5/vendor_perl .) at /usr/perl5/5.6.1/lib/BCBS.pm line 4.
BEGIN failed--compilation aborted at /usr/perl5/5.6.1/lib/BCBS.pm line 4.
Compilation failed in require at /apps/apache/cgi-bin/barcodes/cips/barcode.pl line 4.
BEGIN failed--compilation aborted at /apps/apache/cgi-bin/barcodes/cips/barcode.pl line 4.

I tried installing the module manually several times by compiling the Makefile.pl in the tar but kept getting this error. So I was fiddling around and found how to access cpan.org directly through perl using:

perl -MCPAN -e shell

and installing the Date::Calc mod from there.

cpan> install Date::Calc
Date::Calc is up to date.

I'm still getting the error, although now it's added the bit about BCBS.pm, which was previously the actual .pl code I was executing.

I have two versions of perl on the system I'm running, 5.00 and 5.61, but I've changed the path statement to look for 5.61 first in /usr/local/bin. The beginning of the file in the error message is:

package BCBS;
use Exporter;
use Time::localtime;
use Date::Calc qw(Add_Delta_Days);

$VERSION = 1.00;
@ISA = qw(Exporter);

Is there some noticeable snafu I'm missing here? Any help would guarantee idol worship for at least three continuous weeks, or twenty-one days total of piecemeal worshipping.

Where is your CPAN configured to install stuff?

Also, what does "locate Date/Calc.pm" return?

I didn't change any of the defaults. I don't know if this helps but here is part of the config it runs at startup:

The next questions deal with Module::Build support.

A Build.PL is run by perl in a separate process. Likewise we run
'./Build' and './Build install' in separate processes. If you have any
parameters you want to pass to the calls, please specify them here.

Parameters for the 'perl Build.PL' command?
Typical frequently used settings:

--install_base /home/xxx # different installation directory

Your choice: []

Parameters for the './Build' command?
Setting might be:

--extra_linker_flags -L/usr/foo/lib # non-standard library location

Your choice: []

Do you want to use a different command for './Build install'?
Sudo users will probably prefer:

su root -c ./Build
or
sudo ./Build
or
/path1/to/sudo -u admin_account ./Build

or some such. Your choice: [./Build]

Parameters for the './Build install' command?
Typical frequently used setting:

--uninst 1 # uninstall conflicting files

Your choice: []

I can't find a specific file called Date/Calc.pm but a look for partials returned this:
# find / -name "Date*.pm"
# find / -name "*Calc*.pm"
/usr/local/lib/perl5/5.8.7/Math/BigInt/Calc.pm
/usr/local/lib/perl5/5.8.7/Math/BigInt/CalcEmu.pm
/usr/local/lib/perl5/site_perl/5.8.7/sun4-solaris/Date/Calc.pm
/export/home/user1/perl/Date-Calc-5.4/Calc.pm
/export/home/user1/perl/Date-Calc-5.4/blib/lib/Date/Calc.pm
/apps/apache/cgi-bin/Offsite/Date-Calc-4.3/Calc.pm
/apps/apache/cgi-bin/Offsite/Date-Calc-4.3/blib/lib/Date/Calc.pm
/apps/packages/Calc.pm

I have another question in a similar vein; how can I permanently edit the @INC variable so that I can point it to what appears to be my main repository for modules?

/usr/local/lib/perl5/site_perl/5.8.7/

I know I can do this in each script using "use lib" but that could mean hundreds of changes with all the scripts I have.

symlink /usr/bin/perl to /usr/bin/perl5.8.7 ?

The symlink worked! Now at least I can go back to troubleshooting code instead of this perl install. Thanks, Chris.
