ubuntu 14.04 server perl POSIX install error -


i don't know perl, needed posix dependency script. have configured cpan answering default questions , then, inside cpan, 

install posix

i have been asked million questions, answered default all, , script installing million modules. need ? i'm concerned if goes wrong possible undo ?

update

well, feared happened

everything date. type '/usr/bin/make test' run test suite. ./perl -ilib installperl --destdir=    /usr/local/bin not writable make: ** [install-all] erro 2 rjbs/perl-5.22.0.tar.bz2 /usr/bin/make install  -- not ok failed during command: rjbs/perl-5.22.0.tar.bz2                     : install no

please, how can fix ?

posix core module included perl. don't need install separately. why don't install perl via package manager instead of source?
