After getting sqlite 3.5.3.p3 building on t2 with gcc-4.4.0, Sage is falling over on atlas-3.8.3.p2. Before I waste any time on this, is a fix known, or anyone have any useful information about the problem? I'd rather not waste time on it if the reason for the failure is known, but the fix is

The following is the beginning of the optional phcpack spkg, which tries to get the architecture using python. I am hopeless at bash, I'm sure there are ways to do it that way too: #!/usr/bin/env python import os uname = os.uname() main_arch = uname[0] sub_arch = uname[-1] then for example if

Now that the semester is over, I'm trying to finish the spkg for lp_solve. lp_solve does not use autoconf and make, but rather has its own specialized build scripts for different platforms (mainly Windows, Mac OS X, and Linux/UNIX). What is the recommended way of determining which platform Sage is
