[Stackless] Trouble linking on Ubuntu Linux

[Simon Pickles]

Well, I made a little progress.

I used grep to find PyChannel_new in:

/home/simon/Source/Stackless/release25-maint/libpython2.5.a (the new 
version including stackless?)

and manually copied it over:

 /usr/local/lib/python2.5/config/libpython2.5.a (the old version without 
stackless?)

Then the program compiles and link! Woot I thought!

However I get a seg fault when running it. The debugger in code::blocks 
IDE with g++ points to a problem quite deep in Py_InitializeEx().

I think my manual copy of the library is bad. How come make install 
didn't do that? I guess I've got two copies of python (at least in 
parts) on my machine:

/usr/local/include/python2.5
/usr/include/python2.5

Is this causing some problem? My linux experience is still limited, so 
not so hot on controlling installation locations etc :)

Thanks for any advice
