• pyausaxs - Ebuilds: 2, Testing: 1.1.3
  Description: Minimal pyausaxs stub for Gentoo. Upstream pyausaxs is a Python binding for the AUSAXS C++ SAXS engine and ships only as platform-specific wheels with a bundled libausaxs. SasView imports pyausaxs.AUSAXS at module load time, but guards call-sites with try/except and falls back to its pure-Python scattering calculator, so this stub lets SasView run without the native accelerator.

• pygobject - Ebuilds: 1, Testing: 2.28.6-r55
  Description: GObject is a object system used by GTK+, GStreamer and other libraries. PyGObject provides a convenient wrapper for use in Python programs when accessing GObject libraries. Like the GObject library itself PyGObject is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full featured applications. PyGObject now dynamically accesses any GObject libraries that uses GObject Introspection. It replaces the need for separate modules such as PyGTK, GIO and python-gnome to build a full GNOME 3.0 application. Once new functionality is added to gobject library it is instantly available as a Python API without the need for intermediate Python glue.
