sage:
  synopsis:
    A "viable free open source alternative to Magma, Maple, Mathematica and Matlab,"
    written in Python. Active development, an online Wiki and user community, and
    elegant coding ensure that this looks to be the Matlab-slaughterer we've been
    looking for.... Indeed; I've researched this extensively; and SAGE is, indeed, at
    the Linux forefront of mathematics research. Highly recommended. Yes. However, see
    below...
  building:
    Gentoo provides no viable SAGE e-builds, at the moment. None. This is not due to any
    inherent laziness on the part of the Gentoo crew, but rather the inherent bizareness
    of the SAGE build system; SAGE developers (literally) re-invented the build wheel by
    requiring users desiring to build SAGE from scratch to manually incorporate all SAGE
    dependencies into SAGE-controlled system paths. This is in strong opposition, of
    course, to the customary mechanism by which applications share shared libraries.
    (SAGE has no mechanism to share the libraries upon which it depends with other
    applications! Insane.)
