That's because you're defining configurePhase as an environment variable, so you
need to run it as "$configurePhase" instead of "configurePhase".

FYI, stdenv's setup.sh runs a phase as follows:

  eval "${!curPhase:-$curPhase}"

I.e. it evaluates the contents of the environment variable named after the phase
if defined, and otherwise the function named after the phase.
