The problem was that I was working on a machine with
I needed libtk8.5.so. For administrative reasons :-( I
wasn't allowed to change any files in these two directories,
was only allowed to install in /usr/local/lib, but not
allowed to add /usr/local/lib to /etc/ld.so.conf.
So I had to build python in a way that it found
/usr/local/lib/libtk8.5.so but not the two copies of
libtk8.4.so. This is where I needed to know what libraries
were being loaded at run time.
The solution was to (temporarily) delete the 8.4 libraries,
add /usr/local/lib to LD_LIBRARY_PATH for the python
install, then restore the 8.4 libraries. Tkinter looks for
the 8.5 library now.
