[FLASH-USERS] FLASH compilation

[Ryan Farber]

Hi Carlos,

I think the extra slash character "/" is why you had command not found. In
any case for switching to openmpi (or for fixing the path typo), go to
${YOUR_FLASH_PATH}/sites and then create a directory for your hostname (or
just modify whichever one it is using, usually Prototypes/Linux; in any
case that gets printed during the setup command). You'll want to modify the
paths in Makefile.h.

Best,
--------
Ryan
