New description:

 There are many places within the Sage library that make explicit
 references to `SAGE_ROOT`, when `SAGE_LOCAL`, `SAGE_DATA`, etc. are more
 appropriate. These references assume a particular directory structure
 which unnecessarily break various components when using a different
 directory structure (i.e. transitioning to git or sage-on-gentoo). This
 ticket aims to correct many of these references.

 This ticket also adds `sage.env` as a place to keep global used Sage
 variables (these currently live in `sage.misc.misc`). Currently this file
 does little more than separate out some of these variables, but the intent
 is to provide a dedicated place in python for determining the environment
 for the Sage library (this will eventually need to be independent of
 `sage-env` if we are ever to truly transition to argparse).

 Followup: #14226.

 '''Installation Instructions''':
  * apply attachment:trac13432.patch to the sage library
  * apply attachment:trac_13432-fix_expect.patch to the sage library
  * apply attachment:trac13432_root.patch to the root repository

Comment:

 That was the place. I added a trivial patch to take care of it.
