[Nix-dev] Writing a nix expression to catfish

[José Romildo Malaquias]

Hello.

I am trying to write a derivation for catfish, a Python application. I
have tried the attached derivation.

When trying to build the package with the command 'nix-build -K -A
catfish', I am getting the error that can be seen in the attached log
file.

Any clues on how to fix them?
