Libinit compilation

[Matt W]

Hi,

just a general note: you do need to be quite careful running performance 
tests. It can easily be that your test is not representative of the systems 
you are are going to run in practice.

Whilst all these codes will run this C-240 system. It may be that their 
ability to use symmetry, run 3D periodic systems, scalability to large 
number of processors and other factors, such as local knowledge to get 
help, are going to vary a lot. Depending on what you need for the whole of 
your project, just seeing which one runs this system fastest might not be a 
very sensible cost function.
