I don't believe that. It should be completely impossible to completely install Sage from source and get that error. (1) *Precisely* what file did you download when you write "source code"? (2) What did you type to build from source? (3) How long did building from source take? (4) Exactly what did you type to run Sage after building from source? Can you send an exact log William
