Hi All, I'm curious what the preferred method is for dealing with System Requirements originating from an imported package. For example, if I had a package that imported `biomaRt` which itself imports `XML` which has the SystemRequirement `libxml2` how is that dealt with? Are package installers expected to troubleshoot this (via install messages), should I put this requirement and install instructions for `libxml2` in a README for my package?
I think you should concern yourself only with the system dependencies of _your_ package, rather than trying to track or duplicate indirect system dependencies. If you're not satisfied with the way the original package 'helps' users to satisfy system dependencies, then you should communicate with the maintainer of the original package. That way your users, and indeed all direct and indirect users of the original package, benefit from improved instructions.

Thanks for any input, Zach
