There is a syntax error in one of the files in scientificpython-2.4.3. The error is detected by the newest Python, and the MPI module fails to load (the module should load even if MPI is not available, since it is used to test for availability of MPI. The error is in the fallback code being executed if MPI is not available). Python 2.4.2 (#1, Oct 13 2005, 11:49:59) [GCC 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import Scientific.MPI Traceback (most recent call last): File "<stdin>", line 1, in ?
