Log message:
Mark packages that are not ready for python-3.3 also not ready for 3.4,
until proven otherwise.

Log message:
Mark packages as not ready for python-3.x where applicable;
either because they themselves are not ready or because a
dependency isn't. This is annotated by
PYTHON_VERSIONS_INCOMPATIBLE=  33 # not yet ported as of x.y.z
or
PYTHON_VERSIONS_INCOMPATIBLE=  33 # py-foo, py-bar
respectively, please use the same style for other packages,
and check during updates.

Use versioned_dependencies.mk where applicable.
Use REPLACE_PYTHON instead of handcoded alternatives, where applicable.
Reorder Makefile sections into standard order, where applicable.

Remove PYTHON_VERSIONS_INCLUDE_3X lines since that will be default
with the next commit.

Whitespace cleanups and other nits corrected, where necessary.

Log message:
Replace py-{curses,readline,Tk}/buildlink3.mk with DEPENDS.

There are no buildlink3-relevant files here, just a loadable module.

Log message:
Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.
Mark packages that don't or might probably not have staged installation.

Log message:
PYVERSSUFFIX use in PLIST.

Log message:
Import py26-biskit-2.3.1 as wip/py-biskit.

Biskit is a modular, object-oriented Python library for
structural bioinformatics research. It facilitates the manipulation
and analysis of macromolecular structures, protein complexes, and molecular
dynamics trajectories. For efficient number crunching, Biskit objects tightly
integrate with numpy. Biskit also offers a platform for the rapid integration of
external programs and new algorithms into complex workflows
Calculations are thus often delegated to establisheds
