Altered SIP formula to install from Mercurial repos
Altered SIP formula to install from Mercurial repos

Riverbank has a nasty habit of pulling old tarballs whenever new releases are
made.  New releases are made fairly often--- this leads to a state where the
PyQT and SIP formulae are chronically broken due to outdated tarball links.

This changeset patches the SIP formula to install from the Mercurial repository
for SIP located at:

  http://www.riverbankcomputing.co.uk/hg/sip

By default this formula installs an archived tarball from a tag corresponding to
the released version of SIP.  Tarballs are fetched using HTTP.

If the user has Mercurial installed, bleeding-edge versions can be installed by
specifying the --HEAD switch.
