The developer typically does the following in this case:

1. Rename the binary (in post-install or something) to
pylupdate5-${PYVERSION} and install it as such.
2. Add an ALTERNATIVES file to link the executable to pylupdate5.
3. (and this may be the hardest part) If dependent packages run the
tool, have them run pylupdate5-${PYVERSION} instead.
