First I installed all dependencies.

Everything was fine. Installed perfectly. But could not get core module to install

I tried installing by force but did not work

perl -MCPAN -e "CPAN::Shell->force(qw(install Email::Simple));"
[download]

Tried multiple times with cpan and tried ppm

Looked it up on google. No luck. Tried installing Email::Date::Format again. worked perfectly.

Asked here. Hope someone can help.

tried the below answer as well. Does not show in PPM list.

if you have the activestate distro, go to shell/command prompt, enter PPM. When PPM opens type "remove package name" this will uninstall that particular package for you. type "help remove" in PPM for more details.

Alternativly if you know what files came with the package, just delete them. Be aware that some modules will rely on other modules been installed so make sure there are no dependencies before you remove delete packages.
