We have recently upgraded to using 64-bit R.  Was trying to install
a SOM library by using:


from  http://cran.r-project.org/src/contrib/Descriptions/som.html

I got this error message:
    ld: fatal: file som.o: wrong ELF class: ELFCLASS64

I was able to fix this problem by modifying
R/etc/Makeconf and changed all SHLIB_FLAGS (with -G) to
also include -m64.
