12 Hi Steve,

14 we probably should disable that flag until we have a number of kinks sorted
15 out....
16 Patches and dependencies - in theory we would need to enforce pari[mpir=]
17 and ntl[mpir=]. I will look at these patches later, after I have gone through
18 my other priorities:
19 *ATLAS independence [hoping it will hit the overlay in a few hours]
20 *system singular which has to be read for sage-4.5

27 Yeah! With real CPUs that must be awesome. The cython calls used to be
28 serial and use only one CPU, ccache doesn't do anything about those, so
29 you should have a real benefit on that end. Then the compilation will be
30 parallelized which is good as well.
