Fedora 15 doesn't have 1.6 out yet. I tried to use the binary release but it seems to be compiled against different libssl/libcrypto's than what I have on my system... I symlinked them over but it fails to create the virtualenv still:

sontek@beast$  virtualenv -p /home/sontek/Downloads/pypy16/pypy-1.6/bin/pypy /home/sontek/code/pypyenv2
Running virtualenv with interpreter /home/sontek/Downloads/pypy16/pypy-1.6/bin/pypy
/home/sontek/Downloads/pypy16/pypy-1.6/bin/pypy: /usr/lib64/libssl.so.0.9.8: no version information available (required by /home/sontek/Downloads/pypy16/pypy-1.6/bin/pypy)
/home/sontek/Downloads/pypy16/pypy-1.6/bin/pypy: /usr/lib64/libcrypto.so.0.9.8: no version information available (required by /home/sontek/Downloads/pypy16/pypy-1.6/bin/pypy)

and then the directory isn't created.

1.5 is an old release of PyPy. Try 1.6?
