I'm trying to install PyQt5 on my Ubuntu 12.04 box. So after downloading it from here I untarred it, ran python configure.py and make. Make however, results in the following:

cd qpy/ && ( test -f Makefile || /opt/qt5/bin/qmake /home/kram/Downloads/PyQt-gpl-5.0/qpy/qpy.pro -o Makefile ) && make -f Makefile 
make[1]: Map '/home/kram/Downloads/PyQt-gpl-5.0/qpy' is entered
cd QtCore/ && ( test -f Makefile || /opt/qt5/bin/qmake /home/kram/Downloads/PyQt-gpl-5.0/qpy/QtCore/QtCore.pro -o Makefile ) && make -f Makefile 
make[2]: Map '/home/kram/Downloads/PyQt-gpl-5.0/qpy/QtCore' is entered
g++ -c -pipe -fno-strict-aliasing -O2 -Wall -W -fPIC -D_REENTRANT -DQT_NO_DEBUG -DQT_CORE_LIB -I/opt/qt5/mkspecs/linux-g++ -I. -I. -I../../QtCore -I/usr/local/include/python2.7 -I/opt/qt5/include -I/opt/qt5/include/QtCore -I. -o qpycore_chimera.o qpycore_chimera.cpp
qpycore_chimera.cpp:21:20: fatal error: Python.h: File or folder does not exist
compilation terminated.
make[2]: *** [qpycore_chimera.o] Error 1
make[2]: Map '/home/kram/Downloads/PyQt-gpl-5.0/qpy/QtCore' is left
make[1]: *** [sub-QtCore-make_first] Error 2
make[1]: Map '/home/kram/Downloads/PyQt-gpl-5.0/qpy' is left
make: *** [sub-qpy-make_first-ordered] Error 2

(I translated some parts of the error message from Dutch to English, so some words may be a bit off from the normal wording..)

Does anybody what the problem is here? Where could the relevant Python.h file be?

sudo apt-get install python-dev

Your missing the python header files.

I thought that as well, but I've already got them installed. After running your command it says python-dev is already the newest version. – kramer65 15 hours ago
What version are you installing for and what version of python-dev do you have – Jakob Bowyer 15 hours ago
I don't exactly know how to check the version of python-dev, but I ran sudo apt-get install python2.7-dev, which also told me I've got the latest version. – kramer65 15 hours ago
Is Python.h in your include directory? is the library registered (ldconfig)? Is it the correct version? Did you try manually setting the path for python? – Sebastian Lange 15 hours ago
@SebastianLange - Wow, that's a lot of questions which I don't know the answer to. Which include directory are you talking about? Where can I find that include dir? How can I check whether the library is registered? Which version are you talking about? The version of PyQt (that's 5), or the version of Python (that's 2/7)? I didn't try manually setting the path for python. How would you sgguest I could do that? – kramer65 13 hours ago
