Log message:
Changes 0.7.6:
Fixed Solaris & Solaris Studio support and Python 2.6 compatibility.

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

Log message:
Set modulename so cffi doesn't have to invent them.
Fixes PLIST issues with different compilers.
Bump PKGREVISION.

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:

Log message:
Import py27-xattr-0.7.2 as sysutils/py-xattr.

xattr is a Python wrapper for extended filesystem attributes.

Extended attributes extend the basic attributes of files and
directories in the file system.  They are stored as name:data pairs
associated with file system objects (files, directories, symlinks,
etc).
