Trac #17277: pkgconf depends on bzip2

We should be using the gzipped-tarball, not bzipped. Bzip depends on
pkgconf.

Upstream tarball

Trac #17281: Remove -notebook-ipy from sage -h
17128: fix doctest
Trac #17281: Remove -notebook-ipy from sage -h

That line should not have been added in #16996.

{{{
  -notebook-ipy [...] -- start the Sage IPython notebook
}}}

That command does not work:

{{{
$ sage -notebook-ipy
CRITICAL:root:unknown notebook: otebook-ipy
Error, notebook must be one of default, ipython, sagenb but got otebook-
ipy
}}}

It was decided in #16996 to use the syntax {{{sage --notebook=ipython}}}
instead and we forgot to remove that line.

Trac #17128: Problem with solution_dict=True and solving for multiple variables

This bug was reported at http://ask.sagemath.org/question/24446/problem-
