I am getting this error we have withdrawn our code from backup also. no change in code which was running day before. Guess something wrong with perl installation or perl modules. Guess one developer was installing a perl module -File::Basename which was already installed may be did force install. Dont have any backup to see that. Can anyone help me diagnosis?have tried all this-

no  warnings;
use diagnostics -verbose;
enable  diagnostics;

Writing the code where getting error(though its working fine on another m/c

sub _load_constants {
    my %constants;
    foreach my $constant (@Modules::Constants::EXPORT,@Modules::Consta
+nts::EXPORT_OK)
    {
        if (defined &{$Modules::Constants::{$constant}})
        {
            $constants{$constant} = [&{$Modules::Constants::{$constant
+}}];
            if (scalar(@{$constants{$constant}}) == 1)
            {
                $constants{$constant} = @{$constants{$constant}}[0];
            }
        }
    }
    return \%constants;
}
my $CONSTANTS_ref = _load_constants();

can anyone help me understanding what change has happened in perl modules/perl setup which i can diagnosis further. Have tried even cpan -update to update all the packages & got error-

perl  NWCLARK/perl-5.8.6.tar.gz                    : make NO isa perl

Can you post more of your code please? You have an error on demandbuild-hotel.pl line 8, probably on that line you use Modules::CheckCCRfiles; right? If not, can you post demandbuild-hotel.pl line 1 through 10 here? Put line 8 in bold if possible.

Then, what is going on on Modules/CheckCCRfiles.pm line 6? Can we see that code? Your _load_constants method, is it from Modules/CheckCCRfiles.pm?

And Modules/Util is a CPAN module right? Do you know which version you have?

If you find the solution on your own, can you please post it here? Thank you!
