Aha! The proof is here - great work, this is an spkg or interface
bug.
new-host-2:sage-5.0.beta14 $ ./sage -ipython
Python 2.7.2 (default, May 1 2012, 10:37:32)
Type "copyright", "credits" or "license" for more information.
IPython 0.10.2 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints
more.
In [1]: import sys
In [2]: sys.modules['numpy']
---------------------------------------------------------------------------
KeyError Traceback (most recent call
last)
/Users/.../sage-5.0.beta14/<ipython console> in <module>()
KeyError: 'numpy'
In [3]: import Gnuplot as GP
In [4]: sys.modules['numpy']
Out[4]: <module 'numpy' from '/Users/.../local/lib/python2.7/site-
packages/numpy/__init__.pyc'>
And since if it finds Gnuplot, Sage imports it in interfaces/
gnuplot.py, we have this once both spkgs are installed:
sage: sys.modules['numpy']
<module 'numpy' from '/Users/.../sage-5.0.beta14/local/lib/python2.7/
site-packages/numpy/__init__.pyc'>
So Gnuplot automatically imports numpy, and this interface is called
on startup.

By the way, this is not really optional any more, but apparently
experimental?
Well, gnuplot is experimental, but gnuplotpy is optional. I don't get
that...
Found gnuplot-4.0.0
http://www.sagemath.org//packages/optional/gnuplot-4.0.0.spkg -->
gnuplot-4.0.0.spkg
[ ]
http://www.sagemath.org//packages/standard/gnuplot-4.0.0.spkg -->
gnuplot-4.0.0.spkg
[ ]
http://www.sagemath.org//packages/experimental/gnuplot-4.0.0.spkg -->
gnuplot-4.0.0.spkg
[..................................................]
So that is something that should be fixed too. Any ideas from anyone
on a proper resolution of this?
