renv::restore() on mac is having issues with source package

[yannabraham]

Depending on the architecture and installation the following packages have proven difficult to install:

• XML (missing libxml2 library)
• cytolib (missing crypto library)
• flowWorkspace

Possibly other packages might be involved. Things we have tried but did not solve the issue:

• manually installing missing system libraries and linking them - renv seems to ignore certain options and we could not find a way to force them
• installing the package manually in the system library then using renv::hydrate() to copy it to the project library - even if the version is right renv::restore() still tries to install the library

While this is the intended behavior for productive pipeline, for workshops we may want to add the manual installation script back, and correct issues within the scripts as they arise?

renv has caused serious delays during the Rome workshop - what would be alternative solutions?
