Sorry sorry! Thanks for making that build, by the way.

So... I have found that IPython exposes a bug in GNU readline 5.1,  
sadly enough. This bug causes segfaults when the up-arrow key is used  
under certain situations. Ugh. Fortunately, the extant readline 5.1  
patches solve this issue nicely. Hopefully you'll get a chance in the  
near future to update the Universal MacPython 2.4.3 distribution so  
that it doesn't have this issue.

Also, a related query: Is there somewhere in the Python Framework  
structure that is appropriate for placing dynamic libraries that  
Python would link to? Judicious use of the install_name_tool and  
friends could produce a libreadline.dylib that the python binary  
would expect at a particular relative path from itself. This would  
allow that library to be dynamically linked, yet still live within  
(and be distributed with) the framework. Just a thought -- but it  
might be more work than it's worth.
