Re: bug #551926: python-pip and pip: error when trying to install together


[Cc'ing Adam Kennedy since I'm not sure if he's subscribed to debian-devel]

Since Adam mentions that Perl's pip predates Python's pip by a
significant margin, I think we should close this issue by renaming
Python's installer back to pyinstall. It doesn't seem fair for someone
who came on the scene later (who didn't do the appropriate research,
and who, when prompted with the problem, decided to proceed with pip
anyway) to be able to usurp the namespace from Perl.

I'd personally object to renaming Perl's pip to anything else given
these issues.

An alternative arrangement I'd be open to is:
/usr/bin/pip points to a sh script, which tells the user that `pip'
has been renamed to perl-pip and python-pip in Debian. This way,
neither pip gets the /usr/bin/pip name. However, I'm not sure about
how to do this (I guess it'd need to be handled like the dual-life
Perl modules are, via divert and all that...). Again, I don't think
it's fair for Perl's pip to lose `pip' just because some other author
is a jerk (even if Python's pip just so happened to be packaged
