scons and python3?

[Ronald Klop]

Hi,

For porting mongodb42 I need scons with python3.
There are some attempts on making the scons port flavored, but that did  
not work out.
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237122
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230734
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239792

What is the way forward?
- A port like scons-py3 as a slave port of scons?
- If I could overwrite MAKE_CMD to "MAKE_CMD=python3 ${SCONS}" it would  
help, but it is fixed in /usr/ports/Mk/Uses/scons.mk

Any thoughts?

Regards,

Ronald.
