| Dear Kenneth:
| Let me share you a handy thing I learned. You can get the commands
| that the R packages are built with, along with the source code.  Make
| a directory (this will download a bunch of stuff)
| apt-get source r-base-core

I often recommend that too but ... 
| that should download a tarball of original R source code, a diff file
| that is applied to build R deb, and it will open the code and apply
| the diff.  You can look inside the directory, in a subdirectory
| "debian", where the configure files that control package building are
| kept.

... if all you want is, say, the configure invocation then you are better off
just downloading the associated 'diff.gz' file which will be much, much smaller.


| If you type "dpkg-buildpackage -rfakeroot"  in the directory where all
| that stuff got opened up (the one "above" the debian subdirectory), it
| will build the debian packages.  It would not be an incredibly
| difficult thing to replace that R source package with the new one you
| want to use.  But I don't think you need to.  Just look in the rules
| file under debian subdirectory, you will see the configure statement
| they use.  I think in there you'll also find information about what
| devel packages they assume you have.
| I find it to be a little difficult to revise debian builds, so I don't
| really mean you ought to do that. But you could.  And I often have!
