[GUIDE] Ubuntu repository - maintained by djcj

the tools must be inside a directory with the name "tools". I had changed that at some point

ahhh,... that was the issue I still had binaries inside the main folder and didn't see the tools folder.
-> okay 7z was created properly (would be better if it would be created next to the tools instead of inside the tools folder; nearly overlooked it )

I then called ./build-vapoursynth.sh, but that stopped with:

This command is intended for maintainers to use
it deletes files that may require special tools to rebuild.
