[ You can also get R 2.8.1 for free, see the R FAQ and search Ubuntu, or go
  directly to http://cran.r-project.org/bin/linux/ubuntu ]

So you are working with R 2.7,1 and R 2.6.0. May not be for the faint of
heart as some interfaces do change...

                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You may not get far til you get that sorted out -- you do need R.h from the
right place.

But as others have said, Rtools29.exe is fairly straightforward to use, esp
if you know how to use the R / gcc toolchain on Linux. And the win-builder is
also a very fine service.

Good luck, Dirk
