Fedora?

Nothing I can do about the akarin error.
If you configured Hybrid to explicitly loading the libraries make sure they are named as in the script.
If you did not configure Hybrid to explicitly loading the libraries make sure akarin is found by Vapoursynth.

You can tell Hybrid to use an alternative 'Expression handler' than akarin, which is the default in Hybrid.
Using 'std' should work and tell Hybrid to use: https://www.vapoursynth.com/doc/function.../expr.html
