OK, I downloaded and extracted this one. However, ./configure fails on 
python:

    checking for a Python interpreter with version >= 2.7... python2
    checking for python2... /usr/bin/python2
    checking for python2 version... 2.7
    checking for python2 platform... linux2
    checking for python2 script directory...
    ${prefix}/lib/python2.7/dist-packages
    checking for python2 extension module directory...
    ${exec_prefix}/lib/python2.7/dist-packages
    checking for pkg-config... /usr/bin/pkg-config
    checking pkg-config is at least version 0.9.0... yes
    checking for PYTHON... no
    checking for PYTHON... no
    configure: error: Package requirements (python2 >= 2.7) were not met:

    No package 'python2' found

    Consider adjusting the PKG_CONFIG_PATH environment variable if you
    installed software in a non-standard prefix.

    Alternatively, you may set the environment variables PYTHON_CFLAGS
    and PYTHON_LIBS to avoid the need to call pkg-config.
    See the pkg-config man page for more details.
    configure: error: ./configure failed for xorn

This is weird. First it finds python 2.7 just fine, but then it says it 
isn't there?

I checked, and python2 is present where I would expect it, in /usr/bin:

    $ which python2
    /usr/bin/python2

What am I doing wrong? I also tried running ./autogen.sh before 
./configure, but that didn't change anything. Unfortunately, I am not at 
home in software development at all (the last time I fired up gcc was 
several years ago, for a test version of pcb), so I really need to have 
these things spelled out in detail.

This is also why I hesitated upgrading my machine for well over two 
years, because in my experience, it can take quite a few hours and a lot 
of stress to get these things properly running when building them from 
source.

And oh, could you provide a link to the sources of a stable version of 
PCB as well?

Anyway, your help is much appreciated!
