Brian,

Thanks for the follow-up.

Interesting.  But the R Extensions manual says

  1.10.1 Frontend
  ---------------

  This is a rather general mechanism, designed for adding new front-ends
  such as the *gnomeGUI* package.  If a `configure' file is found in the
  top-level directory of the package it is executed, and then if a
  `Makefile' is found (often generated by `configure'), `make' is called.
  If `R CMD INSTALL --clean' is used `make clean' is called.  No other
  action is taken.
I am talking about the need for 'other action' such as 'make install', say.
Are you suggesting I shoehorn what I want done into the main 'make' target ? 

Yes.  I don't see it as 'shoehorn' -- it is the install step.



Indeed, most GNU software follow the convention of:

configure
make
make install
Surely `R CMD INSTALL` can be augmented to call `make install` as well if the `Makefile` is found. 

Best

Yes, cut&paste error. $PREFIX/lib is of course what I had in mind.

Other cases that may profit from this are

          iii)  Some other 'content' such as CRANberries or the cran2deb
             efforts could use it to synchronise / update SQLite database
             files in agreed upon locations.

       iv)  Web-based R add-ons could possibly use this mechanism to hook
          into the web server.
