In the former command-line package specification syntax, which is still
supported but deprecated, =E2=80=9Cptpython-2=E2=80=9D was taken to mean =
=E2=80=9Cversion 2 of
package =E2=80=98ptpython=E2=80=99=E2=80=9D.  Because of this, you cannot r=
efer to this
=E2=80=9Cptpython-2=E2=80=9D package from the command-line (except with -e).

The solution is to call it differently, like =E2=80=9Cptpython2=E2=80=9D.

Eventually (I=E2=80=99d say after 0.10.1 is released) we=E2=80=99ll remove =
support for
the old syntax and the problem will be gone.

HTH!
Ludo=E2=80=99.
