[FLASH-USERS] Problem with pressure matching in HEDP simulation (Steffen Sander)

[Marissa Adams]

Hi all,

Are you using a parallelized version of hdf5? Thats what you need I think
to get laserslab to compile. You can have your system admins build it, or
build it in your home directory and point to the appropriate lib files in
your makefile.
