MPICH2 currently does not support native atomic primitives for 
gcc/sparc.  It needs to be built with the emulated atomics, which means 
that the application needs to be linked with libopa as well.  In 
general, it is good to use pkg-config to see what all libraries are 
required and link with all of them.
