Date/Manip.pm in ubuntu

[itba]

hi, I had Date::Manip running but I was trying to call a perl program from C++ and it seemed like I needed ExtUtils. so I ran

force install ExtUtils::Embedit did it's thing but now I get the following error

Can't locate Date/Manip.pm in @INC (@INC contains: /usr/local/lib/perl5/site_perl/5.15.2/i686-linux /usr/local/lib/perl5/site_perl/5.15.2 /usr/local/lib/perl5/5.15.2/i686-linux /usr/local/lib/perl5/5.15.2 .) I went into CPAN and ran
force install Date::Manip, but it doesn't seem to work...I get the following error
