Hi Russ,
3 questions:
1. do I understand you coreectly that *sudo make install* does not
install *integral.py*?
2. does *integral.py* exist in the GNU APL *src* directory ?
3. what happens if you build apl and start it in the src directory?
[ That should work without installing the script].
Thanks,
Jürgen

I can confirm with SVN 1940 that 'integral.py' is no longer empty, but
after build and `make install`, the results are the same for me.
I tried manually installing the script into /usr/local/bin since )MORE
indicated APL was looking there, but no help.
When I get some time I can try debugging the dispatch logic with my
setup to see what else might be missing. Thanks for looking into it
anyhow.
