MarsSeed [1] filed a deletion request for python2-httpbin [2]: Very broken Py2 package, missing lots of deps.
It was only used in comprehensive testing of python2-requests. But it's not worth keeping, and this kind of testing is not needed for that module. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-httpbin/
