The problem in general is that your computer does not have SSE3
instructions that were used when building Sage leading to "illegal
instrucion - aborted" errors during the runtime. So we added a check
to warn users about it. So far, so good, but Sage 3.4.1 was supposed
to fix this by introducing an SSE2 only mode and William told me that
he build the Sage in the VMWare image in that mode.
I would suspect this is a SNAFU since the env variable that William
thought would get used SAGE_SIMD_FLAG is not the correct one, i.e. it
is SAGE_SIMD_MODE. So I expect we will rebuild the VMWare image as
well as the farm binaries and SkyNet once again right now :(
Ironically there is a ticket against 3.4.2 to document this in
README.txt - oh well ....
Cheers,
Michael
