I get the same results in /usr or /usr/local. I'm just 
building it in my home directory so as not to keep 
reinstalling different builds of python on top of current 
python users.

The problem is an undefined variable in a library, not a 
missing library (all of which are found).

OK. I've noticed the build is a little different to the ones 
I'm used to.

OK will give it a go

Thanks Joe
