I removed the old enthought package from lib/matplotlib, and added the
setuptools-less 2.6b1 package to lib/. It now installs like pytz or dateutil,
directly into site-packages and only if it is not already available. The only
modification I made to the enthought code was in the version files, which
return '2.6b1-mpl' instead of ''. The sys.path workaround mentioned in the
original post is no longer necessary and has been removed.
Building does not seem to be a problem, just do the usual python setup.py
build, etc. I ran backend_driver on my not-so-speedy home computer:
with traited config:
Backend Agg took 2.77 minutes to complete
template ratio 1.748, template residual 1.187
Backend PS took 2.64 minutes to complete
template ratio 1.666, template residual 1.055
Backend Template took 1.59 minutes to complete
template ratio 1.000, template residual 0.000
Backend PDF took 3.35 minutes to complete
template ratio 2.112, template residual 1.764
Backend SVG took 2.90 minutes to complete
template ratio 1.826, template residual 1.309
and without:
Backend Agg took 2.59 minutes to complete
template ratio 1.898, template residual 1.226
Backend PS took 2.29 minutes to complete
template ratio 1.675, template residual 0.921
Backend Template took 1.36 minutes to complete
template ratio 1.000, template residual 0.000
Backend PDF took 2.92 minutes to complete
template ratio 2.139, template residual 1.555
Backend SVG took 2.91 minutes to complete
template ratio 2.129, template residual 1.541
changes in svn-4156.
