One of my students says good things about Spyder, a Python environment with MATLAB-like features. OK, I'd like to give it a try.
On Mac OS X.
Ah---it need PyQT.
And some optional modules, but I'll ignore those for now.
So the first step is to install Qt.
But there aren't binaries---I have to do that from source.
So I have to get XCode onto this machine (fine, that works, it just takes 30 minutes to download).
And hey, Qt builds---I'm on a roll.
So, go into the PyQT directory, do "python configure.py" to, um, configure it, then run "make".
Good, good, good, then: kaboom. The error message is:
g++ -c -pipe -fPIC -O2 -Wall -W -DNDEBUG -DSIP_PROTECTED_IS_PUBLIC -Dprotected=public -DQT_NO_DEBUG -DQT_CORE_LIB -I. -I/Users/gregwilson/PyQt-mac-gpl-4.7.6/qpy/QtCore -I/System/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6 -I/mkspecs/macx-g++ -I/Library/Frameworks/QtCore.framework/Headers -I/usr/include -F/Users/gregwilson/PyQt-mac-gpl-4.7.6/qpy/QtCore -F/Library/Frameworks -o sipQtCorecmodule.o sipQtCorecmodule.cpp

Er, what? Why does it think I'm trying to build a 64-bit application? Earlier compile lines say:
I've highlighted the "-arch i386" line to show that yes, Qt knows I'm on a 32-bit processor---at least, when it's compiling the files in libqpycore.a. Is it a bug in the SIP build and install? Is it---aw, do I really care? Spyder looks nice, but increasingly, my feeling is that if an application doesn't "just install", I'm not interested: I certainly can't ask students doing Software Carpentry to wrestle with issues like this.
Later: this page helped, but not enough: I've got PyQT 4.7.6 installed (at least, "make / make install" in PyQt-mac-gpl-4.7.6 ran to completion), and "python setup.py install" in the spyder-1.1.5 directory worked, but when I try to run spyder from the command line (/usr/local/bin/spyder), it tells me that it can't find PyQT version 4.4. Don't think I'm going to be introducing my students to it any time soon...
