I've been down this road. If wrapping $r->upload() in an eval block
doesn't solve the problem, it's likely that you need to upgrade
libapreq2 to v2.18 (or newer):

If your Linux distribution doesn't include libapreq2 v2.18 (or
newer), the instructions at the above link provides the steps for
compiling from offical source and upgrading to it.
