R CMD build should fail early for old package versions?

Hi all, Today I had an R CMD build that failed while building a vignette because the vignette needs tidyr (>= 1.0, declared in DESCRIPTION Suggests) but my system had a previous version installed. It did not take me too long to figure out the issue (solved by upgrading tidyr) but it would have been even faster / easier if R CMD build failed early, with an error message that says something like "Can not build package XXX because it Suggests: tidyr (>= 1.0) but tidyr 0.8.3 is installed" Is that possible?
If you list a package in Suggests, your package should work (perhaps with some limitations) without the suggested one. Unfortunately for you, the limitation "can't rebuild the vignettes" is incompatible with building the package, but I don't think there's anything you can put in the DESCRIPTION file to indicate this.
