It's not easy on Linux!  There is a src/Makefile that ignores most of the 
info from how R was built, including CC, CFLAGS andlibrary pats such as 
/usr/local/lib64.  And that's if you can get dieharder built: it gave me 
lots of errors before succeeding.  I managed to build from the SRPM, but 
that installed with the include files without read permissions.

But I've succeeded on Windows, and RDieHarder is now in the CRANextras 
collection (and so can be installed from the menus etc). I'll send Dirk 
separately notes on what I had to do to make it work.
