rrdtool: document Perl binding location
In case a user has a local Perl install (e.g. from PerlBrew) then the installer does not by default install the RRDtool binding for this Perl installation. It picks the system Perl version instead. This patch documents in the warning message how to install the RRDtool binding for the user-provided Perl. Closes Homebrew/homebrew#21564. Signed-off-by: Adam Vandenberg <flangy@gmail.com>
