Sage in F11

[Matthew Saltzman]

Sorry to bother the -devel list with this, but nobody on fedora-list
responded to my question, and I know there is some effort to package
Sage for Fedora.  I hope one of those packagers can help me out.

I've installed sage-4.1 on F11 using the F10 binary installation
tarball.  But when I run sage, it fails with the following error:

        /usr/local/sage-4.1-linux-Fedora_release_10_Cambridge-x86_64-Linux/sage
        ----------------------------------------------------------------------
        | Sage Version 4.1, Release Date: 2009-07-09                         |

        ----------------------------------------------------------------------
        Traceback (most recent call last):

            md5 = __get_builtin_constructor('md5')

            import _md5
        ImportError: No module named _md5

I assume I'm missing a dependency, but what is it?  Or is there something else going on?

Sage worked fine in F10.  This error occurred also with sage-4.0.2 in F11.

TIA.
