Make PyQt an optional spkg

[vbraun]

If you want to use the new IPython QT console you need PyQt (and its dependency sip). This ticket adds the relevant spkgs. Together with zeromq/pyzmq (#12843), I can now run the IPython qtconsole. You need to have qt development libraries already installed in your base system, this only makes Qt available from Sage.

Looks good to me.

Perhaps spkg-install could point out that this doesn't work on OS X:

Perhaps we can make a pySide package as well or instead? I believe pyside doesn't use sip, and is developed directly by nokia.

There is a sip package at #13047 that actually builds. W00t. But then the PyQT package at http://www.stp.dias.ie/~vbraun/Sage/spkg/PyQt_x11-4.9.1.p0.spkg still fails instantly:

gcc version 4.6.3 (GCC)

Cannot find qmake (the Qt make tool)

If you have a private installation somewhere, put a symlink to
qmake into /Users/wstein/sage/build/sage-5.0/local/bin and rerun the PyQt installation.

Replying to @williamstein:

There is a sip package at #13047 that actually builds. W00t. But then the PyQT package at http://www.stp.dias.ie/~vbraun/Sage/spkg/PyQt_x11-4.9.1.p0.spkg still fails instantly:

... because I didn't have Qt itself (an 800MB download!) installed. Now, with Qt installed... it still fails since I don't know how to tell PyQt where Qt is. But I'll work on that.

OK, I strongly object to this getting a positive review without the spkg-install starting with a test if you are using OS X, and if so, gives a huge warning about there being no chance it is going to work (and that it has never, ever been tested on OS X).
