Also Listed In: python
pyneqsys provides a convenience class for representing and solving non-linear
equation systems from symbolic expressions (provided e.g. with the help of

The numerical root finding is perfomed using either:
* scipy: scipy.optimize.root
* mpmath (arbitrary precision): mpmath.calculus.optimization.MDNewton
* kinsol (from SUNDIALS): pykinsol.solve
* nleq2 (ZIB library free for academic use): pynleq2.solve
* levmar (Levenberg-Marquardt): levmar.levmar

In addition to offering a unified interface to different solvers, pyneqsys can
also derive the Jacobian analytically (when using pyneqsys.SymbolicSys). This
is useful since doing so manually is widely recognized as both tedious and error

    Affects: */py*
      Ports using Python via USES=python are now flavored.  All the py3-* ports
      have been removed and folded into their py-* master ports.
      People using Poudriere 3.2+ and binary packages do not have to do anything.
      For other people, to build the Python 3.6 version of, for example,
      databases/py-gdbm, you need to run:
        # make FLAVOR=py36 install

Bump PORTREVISION for ports depending on the canonical version of GCC
defined via Mk/ which has moved from GCC 7.4 t
GCC 8.2 under most circumstances.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/ which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, as a double check, everything INDEX-11 showed depending on lang/gcc7.

Use PY_FLAVOR for dependencies.

FLAVOR is the current port's flavor, it should not be used outside of
this scope.
