It could be an OS X thing.

Hi,
I am not sure where to send these, but I figured the following would
be rather nice:
- Sage mode (at least in my setup) is bound to one Sage instance. But
if one plays with SPKGs one may have many. Hence, if sage-mode could
figure out the copy of Sage to use automatically, or I could set it

Lets make a spkg first since it needs to be done anyways and then I don't
have to fiddle with the installation.
Please post your code, even (especially) if it doesn't work.

0. This thread is about building Sage in a virtual machine, not using the
pre-made VM image
1. Its 7G. Harald, can you change this on the web page?
2. Yes. You can use your host browser (http://localhost:8000) to download

I'm not sure I agree with the "ONLY" below. One could argue that the
right kernel matrix of A should at least be a matrix B such that A*B=0
(and with other properties, of course, something like any other B'
with A*B'=0 should have the form B'=B*C for some C...).
