Ty Sarna writes: The following patches (relative to 1.5.2b1) enable Python dynamic loading to work on NetBSD platforms that use ELF (presnetly mips and alpha systems). They automaticly determine wether the system is ELF or a.out rather than using astatic list of platforms so that when other NetBSD platforms move to ELF, python will continue to work without change.
