Python bindings for the GtkSourceView widget
GtkSourceView is a text widget that extends the standard GTK+ 2.x text
widget GtkTextView. It improves GtkTextView by implementing syntax
highlighting and other features typical of a source editor.
.
This package contains the Python bindings for GtkSourceView, and allows
to write Python programs that use the GtkSourceView widget.

I'm getting a 404 not found for the buildbot links

You should be able to right-click the link and save as.

I tried again several times and it fails.

How would the wrong kernel be installed when I follow your instructions exactly as they are set forth?
This is neither quick nor easy if it repeatedly gives corrupted files and others are also having problems getting your instructions here to work.

I tried on two different machines.
