[Users] Question: odd compilation failure

[Richard O'Shaughnessy]

Hello,

While setting up a local cluster, I've run into a problem I just don't understand when compiling.   It seems that the compiler's not finding <math.h>!  (for one program, at least)  To this point, the compilation procedure has proceeded without trouble; I've successfully compiled on other machines.

Thoughts?

Thanks,

-Richard

PS: for reference, the compilation is below

[oshaughn at hydra Cactus]$ ./simfactory/sim build --thornlist=manifest/einsteintoolkit.th  --optionlist=simfactory/optionlists/hydra.cfg
</cut>
