Yes, the kinds package is one of those parts of Numeric which ends up 
being distributed in different manners by different packages.  I 
typically build numeric from sources, so I end up with it installed in full.

> The gnuplot error is still there though...



It is caused by the fact that I'm trying to enable mouse support, but 
unfortunately I think only the CVS gnuplot has this.  In a sense it's 
forcing a bit the users's hand, but I've left it in because Gnuplot with 
mouse is so incredibly better than without, that it's worth for users 
the pain of moving over to CVS code.  I figure that anyone who wants to 
use ipython for scientific work can deal with CVS :)  Being able to zoom 
in with the mouse into a specific region of a dataset, or to rotate a 3d 
plot is so far superior to typing ranges by hand, that the upgrade is 
worth the effort.  So I've deliberately left the error message in as a 
not-so-subtle hint :)

Unfortunately I don't know of a way to trap the error to inform the 
users of all this more gracefully.  Ideally I'd check for this in some 
manner and give a nice message, but because of the way ipython 
communicates with gnuplot, I've failed so far.

So in summary, either set gnuplot_mouse to 0 in 
IPython/GnuplotRuntime.py, or upgrade your gnuplot.  I heartily 
recommend the latter :)
