Hi! edit: also, yum install perl-Crypt-SSLeay

WWW::Salesforce uses LWP::UserAgent as its method of transport.

In order to ensure your machine can communicate over SSL, you'll need to install the LWP::Protocol::https module.

sudo yum install perl perl-core perl-local-lib gcc make openssl-devel 
+perl-Crypt-SSLeay
eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)
echo '[ $SHLVL -eq 1 ] && eval "$(perl -I$HOME/perl5/lib/perl5 -Mlocal
+::lib)"' >>~/.bashrc
cpan App::cpanminus
cpanm LWP::UserAgent LWP::Protocol::https WWW::Salesforce

The above should put you in a better position.

The usual convention is to install modules in some place designated by local::lib. This way, you aren't going to have to worry about your yum updates breaking your Perl modules.

You also won't have to worry about overwriting one of the system modules that may cause some system Perl application to break.

Discussing such matters in IRC will result in the fastest communication with the community to understand this concept. System-Perl == bad (generic, broad-sweeping statement).
