[R-SIG-Mac] Installing Rmpi on Mavericks

[Prof Brian Ripley]

It would be more convenient to use the environment variables, e.g. for 
Fedora I use

setenv RMPI_INCLUDE /usr/include/openmpi-x86_64
setenv RMPI_LIB_PATH /usr/lib64/openmpi/lib
setenv RMPI_TYPE OPENMPI

And 'brew' was not mentioned: you would need to install *that* first. 
But it is unnecessary: openmpi builds out of the box using the compilers 
used for R and needs no customizations.

In view of another thread today, does that clobber other compilers in 
/usr/local?

Please do read the posting guide and what it says about that.
