I've reverted trusty-updates from 1.5.4-1ubuntu3 to 1.5.4-1ubuntu1, and it's fixed on archive.ubuntu.com. If you're using a different mirror, it may be a few hours until it's fixed for you.

The failure here is python-pip-whl, not python-dev-all. The bug title was wrong, I corrected it.

  python-pip : Depends: python-pip-whl (= 1.5.4-1ubuntu3) but it is not going to be installed
is the actual failure. The later message
   Recommends: python-dev-all (>= 2.6) but it is not installable
is only informative, since it's only a recommended package. I filed bug 1495708 "python-pip recommends nonexistent python-dev-all package"

(For what it's worth, this bug seems fixed in Vivid 15.04, python-pip no longer depends on python-pip-whl.)
