[Scons-users] installation to virtualenv broken in scons 2.5

[Noah Hoffman]

Hello,

Installation to a virtualenv appears to have broken in the latest
release of scons. Please let me know if information in addition to the
commands and output below would be helpful. I have reproduced the
issue on both OS X (el capitan) and Ubuntu 14.04. Note that I see the
same behavior when installing v2.5 to a fresh virtualenv (as opposed
to an upgrade from 2.4.1 as shown below).

Thanks for having a look.

% python --version
Python 2.7.10
% virtualenv --version

% virtualenv scons-env
% source scons-env/bin/activate
% pip --version
pip 8.1.1
% pip install scons==2.4.1
% hash -r
% scons --version
