No, we have not discussed about SCons. To me it looks as a great
replacement for distutils. Though it supports currently only C
compilations, one could easily add Fortran support.

However, I don't think that we should move to using SCons right now for
the following reasons:

1) Current scipy_distutils serves scipy needs regarding building extension
modules quite well, including Fortran support. scipy_distutils may need
some polishing when using it with other platforms than Linux,Win32 and
other Fortran compilers than g77. Using current SCons would not ease this
task as it lacks the same things as distutils. And scipy_distutils already
has most of the required hooks implemented.

2) SCons does not solve our autoconf problem. As you said, it's more like
a make replacement. And I think your proposal with Eric's modifications
will be quite adequate for scipy needs.

May be Eric has more to say about QMTest. I have not really looked at
Eric's testing framework yet and therefore I have very little to say 
about testing except it is 'must to have'.
