To build on Solaris 10 (or OpenSolaris) it would need to work with python 2.4.4. drkir...@kestrel:~$ python Python 2.4.4 (#1, Jan 10 2007, 01:25:01) [C] on sunos5 Type "help", "copyright", "credits" or "license" for more information. I can see there might be even more Solaris issues! Since python 3 is not backward compatible with python 2, there could be even more problems in future. Personally I would have stuck to POSIX scripts until python in Sage was built.
