In most cases a tarball built with an older version of R will be usable 
in a newer version without any problem.

Older versions may not be able to handle a tarball from a newer version, 
but I can't remember the last time we made changes big enough for that 
to happen.

Perhaps you are doing a binary build (e.g. a .zip file in Windows)? 
Those are tied to specific versions; the source builds generally are not.
