[SciPy-user] Incorporating SUNDIALS in SciPy

Filed under Bug 74356, also see lam-mpi Bug 62561. (Needs the updated
lam-mpi ebuild to build with fortran support, also compile your gcc with
fortran flag set. I don't know how to enforce this in an ebuild)

Any feedback on how to write better ebuilds are welcomed,
	Jan-Jan
