Hi William, Thanks for your reply!
Something has turned up that I must attend to, so I cannot try your

Dear Supporters,
the following works:

Sage version: 3.3

I can't get it to work. Could you be a bit more specific with the
details (I really have no clue).
The idea is that I upload the file to VMware Player and then load the
file in Sage, right??? Should I do the Data-Upload before I start
Sage? What would the exact syntax be if the Sage-file is
Dear all,
I had a great idea (so I thought) about upgrading in the background
while the sage server is still running. Here is what I did, but it
didn't work for some reason: In OS X 10.4, I shut down the server

I'm trying to build sage from the source on our cluster.
The cluster is running under SLES9SP3 (all AMD Opterons).
We are normaly using PGI compiler (8.0.X) for fortran. The

I tried to set F77, F90 and so on and also tried

I am updating Sage on OSX 10.5. This is in a computer lab with about
40 machines. There is an existing version of Sage on the machines.

Hello,

We should really upgrade.
The current version just has different bugs compared to what we

But it seems that 5.18.x out in April ought to fix some annoying bugs
