[Nix-dev] Enlightenment 18 - error with cpufreq module

[José Romildo Malaquias]

Hello.

When starting the enlightenment version 18 desktop manager on my
unstable nixos system, I am getting the following error regarding the
cpufreq module:

  Enlightenment Cpufreq Module:
  There was an error trying to set the cpu power state setting via the
  module's setfreq utility.

  Cpufreq Permissions Error:
  The freqset binatry in the cpufreq module is not owned by root or does
  not have the setuid bit set. Please ensure this is the case. For
  example:

  sudo chmod u+s,a+x /nix/store/dbwa7pdwc0wzng07kccmmghsasw7jkqf-enlightenment-0.18.8/lib/enlightenment/modules/cpufreq/linux-gnu-x86_64-ver-00/freqset.

Is this a bug with the e18 derivation?

Any clues?
