[Rd] Internet access and R CMD make check-devel

[Gabriel Becker]

Thomas,

In my experience, as pointed out also by Gabor, its often part of the
devops build process to remove/comment out these tests or otherwise modify
them so that they will pass (if they SHOULD pass) in your environment.

That said, a quick look at the Makefile does suggest that failing on the
internet tests should be "allowed" and not cause the whole process to
return a non-zero value.

I don't have time right this second to test this though. Is that not the
behavior you're seeing in practice? Or do the tests hang so the process
never completes, or...?

Best,
~G
