Plotting broken on MacOSX

[GoogleCodeExporter]

What steps will reproduce the problem?

aes248203:scitools-0.7 $ sudo python setup.py install --easyviz_backend gnuplot
after except!!!!!!!!!!!!!!!!
default scitools.easyviz backend becomes gnuplot (could be set by the 
--easyviz_backend option to setup.py)

Could not import module "Gnuplot" - it is not installed on your system. You 
need to install the Gnuplot.py package.

Also,

>>> from scitools.std import *
scitools.easyviz backend is gnuplot
>>> x = linspace(0, 1, 51)
>>> plot(x, sin(x))
Traceback (most recent call last):

What is the expected output?

A plot of the sine function.

 What do you see instead?

Nothing.

What version of the product are you using? On what operating system?

MacOSX 10.6.6, python 2.6 installed via MacPorts, Scitools 0.7

Please provide any additional information below.

Please note that both gnuplot and Gnuplot.py are installed on my system and 
work fine. In particular,

$ gnuplot
Terminal type set to 'aqua'
gnuplot> plot sin(x)

works as expected, as does

$ python
>>> import Gnuplot
>>> from numpy import *
>>> g = Gnuplot.Gnuplot(debug=1)
gnuplot> set terminal aqua
>>> x = arange(10, dtype='float_')
>>> y1 = x**2
>>> d = Gnuplot.Data(x, y1)
>>> g.plot(Gnuplot.Func('x**2'))
gnuplot> plot x**2 
>>>

Hi, can you please check if you still see this issue in SciTools 0.8 (released 
today)?
