That worked, thank you.

The Tip in 43.1 did not explain in that much detail.  I searched but could
not find that explained anywhere in the docs.  Your paragraph would be
a nice enhancement to the tip.

 I do not think you can do it like this:

 > make distclean
 > ./configure --with-openssl --with-libxml
 --with-libxslt --with-python PYTHON=/usr/bin/python
 > make
 > ./configure
 --with-openssl --with-libxml --with-libxslt --with-python
 PYTHON=/usr/bin/python3
 > make
 > make install

 You need to configure and make one way, then
 install, then make distclean,
 reconfigure
 and remake the other way, then make install in only the
 src/pl/plpython directory.  The recipe as you
 have it will end up with
 only one installed
 copy of plpython, not two, and I'm not real sure that
 that copy will be correctly built for either
 case.
