Sorry for the earlier mail: Send got pressed on a half-cooked mail :-)

Heres a cleanup.
--------------------------------------------------------------------------

Build-tools like scons rethink make's "older timestamp => rebuild"
model.  You may want to look at one such.

From http://www.scons.org/architecture/index.html

> (S)Cons decides if a file was out-of-date by using MD5 checksums of the contents of

SCons also comes to mind because you are using make for R not
(traditional) programming

[Again from the above link]
> Most of the build tools just mentioned were written by programmers and for
> programmers.

....

> (SCons arose from a)

> including a build tool, that  would be accessible not only to programmers but also to
> computer users such as physical scientists.


[Disclaimer: Ive not tried Scons myself]
