This one gets rid of the extra "usr" subdirectory that we had and now fits the format that pyenv expects

Add pyston-2.3.1 support

We changed the directory structure for pyston 2.3.1 slightly, where we now
include a top-level "pyston-2.3.1" directory when you unpack the tarball.

Don't update conda when installing pip

Now that Travis check has been removed from the repo

Required to prevent a crash when no verbosity given.

In GNU `sed`, the `-iEe` argument is equivalent to `--in-place=Ee`, which would create `~/.profileEe` as backup of `~/.profile` if the command executed successfully. However, because the `e` is no longer being processed as an expression argument, `sed` does not correctly join the expressions and exits with `sed: -e expression #2, char 10: unexpected }`.

The intent is to use extended regex, perform the changes in-place, and use a series of expressions, so `-Ei -e` is used instead.

This is essentially the same fix as in pull request #2047, but it
is applied from Python 2.6.6 to 2.6.9, and for `ossaudiodev` as well
as the (deprecated) `linuxaudiodev`.

With the normal `setup.py`, the installation of the `ossaudiodev`
module is skipped under GNU/Linux with newer kernel versions because
Python 3.1 appends the major kernel version to the result of
`build_ext.get_platform` and later `ossaudiodev` is skipped if the
major kernel version is not 2. A similar problem might occur if
installing in FreeBSD.

This problem may even occur if installing Python 3.1 in a Docker image
of an old OS (e.g. prehistoric Debian or CentOS), because the major
kernel version is still the one of the host system.

The solution is to use `str.startswith` and only check that the
platform starts with 'linux' or 'freebsd'.
