[Scons-dev] Would requiring Python 2.7.4 or above be a problem for future release?

[Ivan Van Laningham]

Hi All--
The trouble with requiring a minimum of 2.7.x on all platforms is that it
would be problematic for people on CentOS, Redhat and related distros
earlier than say, CentOS 7.  7 has 2.7, but 6 has 2.6 (and not the latest
version, either).  Anyone who wanted to use CentOS 6 would have to install
Python 2.7.x to use Scons.  Might not want to do it, or would go with an
earlier version.

Metta,
Ivan
