Re: [Matplotlib-users] Cannot build matplotlib-0.63.4

[Chris <rea...@po...>]

Thanks very much.

It worked - (mostly)
I made the change you suggested and resolved that error - unfortunately it 
still did not build with pygtk-2.3.97 so I replaced that with pygtk-2.2.0 and 
it worked. Below is the error I got with pygtk-2.3.97 - it appears to be the 
same as an error reported already on matplotlib-users under the title 
'[Matplotlib-users] matplotlib and pygtk 2.3.96'. It seems that in that case 
upgrading to pygtk-2.3.97 helped, but here it did not. But I have a working 
matplotlib and I don't really care what version of pygtk I have to that is 
fine for me.
