Viper client fails to install on nixos

[a-usr]

Here is the useless log:

I'm guessing the build hooks for our way of building viper has changed - though I'm not sure, I haven't used (nor looked at) the viper package for a while. I'll try to take a look.

I can confirm this issue. My log ends in a similar error:
/nix/store/dk1q4pj1d824fm7kvpryc4nmikb5hbih-make-shell-wrapper-hook/nix-support/setup-hook: line 7: die: command not found error: builder for '/nix/store/yygrbi4fhbqwy5swlgw1y48pgxikmjsz-viper-1.8.5.drv' failed with exit code 127 error: 1 dependencies of derivation '/nix/store/vpmihgi3f1b8kj6zkvvbp52azmhqfm59-system-path.drv' failed to build error: 1 dependencies of derivation '/nix/store/0av66r1zhdikz6czz07ndydjr1jjqbjv-nixos-system-nixos-24.05.3214.575f3027caa1.drv' failed to build

looking through the rest of the log i cant seem to find a root cause on my config
