Fernando,
	Thanks for the reply. Output is as follows:

****************

bluey agl # eselect python list
Available Python interpreters, in order of preference:
   [1]   python3.5
   [2]   python3.4
   [3]   python2.7 (fallback)
bluey agl #

****************
Notice there is no asterisk indicating an "active" version as I would 
expect, like if I list opengl, opencl, ruby, binutils and others.

When I noticed this, I ran python-updater and got:

****************

bluey agl # python-updater
  * Starting Python Updater...

  * Active version of Python 2:       2.7

Pretending to run the emerge gives me:

****************
bluey agl # emerge -vp sys-devel/llvm
  * WARNING: The FEATURES variable contains one or more values that
  * should be disabled under normal circumstances: keeptemp keepwork

These are the packages that would be merged, in order:

	As the error happened during the install phase, I changed from 
"emerge...." to "ebuild llvm install". When this runs, the first line 
that is output is the following:

python-exec: EPYTHON value invalid (/usr/bin/python2.7).

	Anything else you need?

	Regards,
		Andrew
