Hi Mark,

We fixed this issue a while back.

You can apply the following patch
http://flash.uchicago.edu/~cdaley/FLASH3.2_patches/fix_mpi_calls/fix_mpi_calls.diff 
<http://flash.uchicago.edu/%7Ecdaley/FLASH3.2_patches/fix_mpi_calls/fix_mpi_calls.diff>

but a better solution is to update to the latest version of FLASH.
