_intel_fast_memset error - any ideas?

[Robin Wilson]

Hi,

The supercomputer admin guys got back to me today and we worked out what 
the problem was. They have a 'module' system where you can load various 
different libraries (various different versions of the GCC and Intel 
compiler suites, and various other tools and libraries) and it was 
configured so that it loaded some strange libraries by default with python, 
but without loading *all* of the required libraries.

Basically, by forcing it to just load a normal GCC compiler, I could 
reinstall (which recompiled using GCC) and then it worked fine.

Thanks,

Robin
