I know this is a modest laptop, but it seems to be in the tuning
section that the Atlas install fails after 12 hours or so.
Here is the last section (STAGE-2) of the install.log;

sage: An error occurred while installing atlas-3.8.3.p16
Please email sage-devel
explaining the problem and send the relevant part of
of /home/reg/Downloads/sage-4.6/install.log. Describe your computer,
operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/home/reg/Downloads/sage-4.6/spkg/build/atlas-3.8.3.p16 and type 'make
check' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
(cd '/home/reg/Downloads/sage-4.6/spkg/build/atlas-3.8.3.p16' && '/
home/reg/Downloads/sage-4.6/sage' -sh)
When you are done debugging, you can type "exit" to leave the
subshell.

===========================================================================
This is on Ubuntu 10.10 Linux that had been updated via Update Manager
and Synaptics Package manager only minutes earlier.
I think all the pre-reqs were met.
The whole install log is about 28Meg..... can't see posting THAT (-:
