I can’t find make or gmake, and my life depends on it
When I tried to install perl-5.18.0 in CentOS 6.4, I got the following error: ‘I can’t find make or gmake, and my life depends on it. Go find a public domain implementation or fix your PATH setting!’ The error message is shown in Figure-1.
[Figure-1]
I then did a group install of “Development Tools’ using yum command, as shown in Figure-2.
[Figure-2]
After installing Development Tools in CentOS 6.4, the error went away and I could install perl-5.18.0.
CPAN error please check the validity of the index file

To install a module from CPAN in CentOS, we need to install perl-CPAN module. After it is installed, we may use interactive shell by using the command: “perl -MCPAN -e shell”, or we can also use ‘CPAN’ command to install a cpan module. When I tried to install a CPAN module, I got an error: ‘Please check the validity of the index file by comparing it to more than one CPAN mirror’, as shown in Figure-1.
[Figure-1]
It looks as if the something got corrupted in cpan installation, I tried to remove the ‘.cpan’ directory from inside root, as shown in Figure-2.
[Figure-2]
After deleting ~/.cpan directory, I uninstalled perl-CPAN module from CentOS, using the command: ‘yum remove perl-CPAN’, as shown in Figure-3.
[Figure-3]
After uninstalling perl-CPAN module, I did a re-install of this module using yum, as shown in Figure-4.
[Figure-4]
Yum searched for its dependencies that are not installed and listed it as shown in Figure-5. In this case, only the package needs to be installed as all dependencies are already installed. Press ‘y’ to continue installing all packages.
[Figure-5]
It installs the perl-CPAN module along with all of its dependencies as shown in Figure-6.
[Figure-6]
Now, if I try to install CPAN modules with ‘cpan’ command or try an interactive shell using ‘perl -MCPAN -e shell’, it all worked fine and the problem ‘Please check the validity of the index file by comparing it to more than one CPAN mirror’, got FIXED.
Can’t locate CPAN.pm – Fixed

To install Perl modules from CPAN using an interactive shell, we use the command:
perl -MCPAN -e shell
If we type this command in CentOS 6.4, we get an error as shown in Figure-1
[Figure-1]
If we get an error “Can’t locate CPAN.pm”, it means that the module ‘perl-CPAN’ is not installed in CentOS. This package comes pre-bundled with CentOS and we have yum configured correctly in CentOS, we can install this module as shown in Figure-2.
[Figure-2]
When we use yum to install perl-CPAN module, it looks for its dependencies and lists them as shown in Figure-3.
[Figure-3]
Once we press ‘y’ to continue installing the package along with its dependecies, the package is installed in CentOS. After installing the package, when we issue the command again: perl -MCPAN -e shell, we get an interactive shell prompt, as shown in Figure-4 and the problem “Can’t locate CPAN.pm’ is SOLVED.
[Figure-4]
Installing perl-CPAN modules solves the issue ‘Can’t locate CPAN.pm in @INC’.
