As we found out in
[http://trac.sagemath.org/sage_trac/ticket/12369#comment:189], you cannot
use the Sage shell to install Sage packages.
The problem is that `sage-env` has some conditional commands. One of
these commands is setting `LD_LIBRARY_PATH`. With #12405, only existing
directories are added to `LD_LIBRARY_PATH`. Upon entering the Sage shell,
`$SAGE_LOCAL/lib` might not exist yet, so that directory isn't added.
Since now `SAGE_ENV_SOURCED=1`, the variable `LD_LIBRARY_PATH` is not
changed anymore. Similarly, `PYTHONHOME` and `PYTHONPATH` are only set
when Python has been installed.
This ticket is about adding a warning when running `sage --sh`. After the
patch:
{{{
$ ./sage --sh
Starting subshell with Sage environment variables set. Don't forget
to exit when you are done. Beware:
* Do not do anything with other copies of Sage on your system.
* Do not use this for installing Sage packages using "sage -i" or for
running "make" at Sage's root directory. These should be done
outside the Sage shell.
Bypassing shell configuration files...
Note: SAGE_ROOT=/usr/local/src/sage-5.0.beta8
(sage-sh) jdemeyer@arcanis:sage-5.0.beta8$
}}}
'''Apply''' [attachment:12698_sh_beware.patch​] to SAGE_ROOT.
