these, which are instructions actually:

That worked. make compiled it without errors whatsoever.

The patch did look like this below:

I already told you about the schedule...

And I'll try and use the rest of your instructions, as can be read at:

http://lists.cinelerra-cv.org/pipermail/cinelerra/2016q2/004678.html

The remaining part [PASTING]:

If this does not report errors, then run:
make install >> log

on the oft chance that it actually builds on the first try, I would
copy the bin directory to a a good spot, and reset the file permissions
to match the needed user/group etc...

mkdir /opt
cp -a /<build_path>/cinelerra5/cinelerra-5.1/lbin /opt/cin
chown -R "owner:group" /opt/cin
