Comment (by jhpalmieri):

 Channeling Nathann: regarding changes like `sage -i cryptominisat &&
 make`, do we need to say something about being in `SAGE_ROOT` first?

 This is no longer a stopgap, so in `misc.package.install_package`, should
 we be returning some other error message? Maybe `NotImplementedError`? I
 agree that `install_package('blah')` won't work much of the time for the
 reasons you give, so a deprecation isn't the right course of action, but a
 stopgap implies that the situation is temporary and is going to be fixed.
 This situation may be temporary, but only in the sense that
 `install_package()` may be completely deleted eventually. Also, with a
 stopgap, you only get the message the first time you run it. If we raise
 an error, you will get it every time, which might be better.

 I'm not sure if the changes to `trac.py` belong here or on a separate
 ticket. I don't care that much, though.

 Also, please make the following change (or something similar):

 Also, the sentences at the top of that file describing Sage packages are
 outdated and should probably just be replaced with a pointer to the
 Developer's Guide. If you are willing to do that, too, that would be nice.
