Having dealt with this before, I recall that a couple of years ago the R programming language provided a native, builtin function to detect the location of a command on $PATH. 

This is similar to how python has `shutil.which`.

The R programming language being the R programming language, the standard library function was, of course, a thin execve() wrapper around `/usr/bin/which`, truly a brilliant and innovative move for a ***standard library***.

I don't anticipate this having changed since then; the configure error is assuredly there to tell you that `which` is an expected runtime dependency. There's no actual solution here other than to add an RDEPEND.

Terribly unfortunate for the 3 users of R. :)
