Hi Armin, I'd like to second the complaint by Michal.

In what concerns your question, please have a look here: http://docs.python.org/2/install/ For arch-indep modules (purelib), everything is clear, the default install location should be just $prefix/lib/pypyX.Y/site-packages so it's a matter of - 'purelib': '$base/site-packages', + 'purelib': '$base/lib/pypy{}.{}/site-packages'.format(X, Y), One could argue that every pure-Python module that is compatible with PyPy declaring compatibility with a given version of Python should be available for this version of Python as well and so go to pythonX.Y rather than pypyX.Y, but I'm not sure whether this is a good default. In my opinion, it's better to leave this up to the distribution packagers and policy makers. For binary extensions (platlib), the path depends upon the implementation of multiarch for every specific distribution. For Red Hat, for instance, the packages containing binary extensions should go to $prefix/lib64/pypyX.Y/site-packages on x86_64 systems and to $prefix/lib/pypyX.Y/site-packages on i386 systems. I'm not sure how this is implemented for CPython though, maybe Michal can comment on this. I know that in CPython you have platlib and purelib, which are defined in sysconfig.py and can be overridden from the command line. Probably the distributions patch sysconfig.py in their packages, because from what I recall the CPython default is to use lib for both platlib and purelib. I guess that PyPy should ideally follow suit... > More importantly, why do you need to specify any "--prefix" at all? I hope that Michal will correct me if I'm wrong, but from what I know, it's a distribution policy in SuSe for Python packages. I don't quite understand the reasoning behind this choice, but it has something to do with staged installation, which is the way the packages are built. Somehow, the PYC-files are not properly generated if the --prefix is not specified... Hope that helps, -- Sincerely yours, Yury V.
