Installing Python eggs under PyPy

Question

How do I install Python egg under PyPy?

During installation, PyPy created /usr/lib64/pypy-1.5/site-packages/ directory. So, I tried using easy_install with prefix set to this directory, however it complains that this is not a valid directory for eggs. Do I just copy eggs from /usr/lib/python2.7/site-packages, or is it as easy as using easy_install (with some changes in configuration, perhaps)?

My working environment is Fedora 15 Beta, Python 2.7.1 (/usr/bin/python), PyPy 1.5.0-alpha0 with GCC 4.6.0 (in /usr/bin/pypy, installed from RPM using yum), easy_install version is: distribute 0.6.14 (usr/bin/easy_install).

First, you need to make sure that you have distribute installed specifically for PyPy. I don't know how fedora packages things, but in general installing a package for cpython does not make it available also for PyPy. In particular, /usr/bin/easy_install is probably CPython-only.

If you use a "normal" install of PyPy, you have this directory structure:

• /opt/pypy-1.5/
  • bin/
  • site-packages/
  • lib-python/
  • lib_pypy/

Then you can download http://python-distribute.org/distribute_setup.py and execute it:

$ /opt/pypy-1.5/bin/pypy distribute_setup.py

Now, you should have /opt/pypy-1.5/bin/easy_install, which will install packages inside /opt/pypy-1.5/site-packages.

However, I have no clue how pypy is packaged in fedora. It it's "just" installed in /usr/bin, then there are chances that installing distribute will overwrite the original cpython's /usr/bin/easy_install.
