[lsst-dm-stack-users] A test development version of Winter'14 stack

[Chris Walter]

Hi Michael,

I think what Mario is saying is that the configure etc is only relevant for building of EUPS itself.  For that you don't care about matplot lib etc.  He is recommending that eups is built with the system python so it doesn't depend on anything else and doesn't break if alternative pythons get wiped out.

Building the actual DM stack is where anaconda or fink is relevant.

Is that right Mario?

Otherwise I have to install Anaconda (easy enough, I hear; but I wanted to keep this simple).  The system Python numpy is 1.6 and matplotlib is 1.1 which are older than the requirements.

But for many users who are just using eups to install the LSST stack this is somewhat the same.
