In the former command-line package specification syntax, which is still
supported but deprecated, “ptpython-2” was taken to mean “version 2 of
package ‘ptpython’”.  Because of this, you cannot refer to this
“ptpython-2” package from the command-line (except with -e).

The solution is to call it differently, like “ptpython2”.

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

HTH!
