Get SVP working

[Maxwell-lt]

Currently I have SVP installing and patching fully. However, for some reason SVPManager is crashing with an error thrown by Zenity:
This option is not available. Please see --help for all possible usages.

I'm not sure how to debug this issue, so far I have tried using strace to get the Zenity command being run by SVPManager, but running this Zenity command standalone doesn't trigger the error.

Pinging @OpenSourceAnarchist since they expressed interest in getting SVP packaged for NixOS last year.

Hello,
I found a NUR package that makes SVP available, c.f., NixOS/nixpkgs#64344.

P.S.
Thank you for your system configuration, it helps to kickstart the jump onto the Nix train ;)
