If LAM/MPI was built as static libraries, yes you will either need to
install the new version of LAM into a new location or recompile every
application that linked in the LAM libraries. If the R module linked
in the static libraries, then yes, it would have to be recompiled.
This is one of those places where shared libraries has some benefit -
LAM's public API has been pretty stable for a while, so generally
upgrades can happen without recompiling applications. Of course, it
does introduce the whole LD_LIBRARY_PATH issue ;).
