If you are on Guix System and find that you need /usr/bin/env, you are
already a "power user": you are venturing outside of what is provided by
Guix alone.

At that point you are expected to read the manual.  Grepping for
/usr/bin/env there will show you exactly what you need to do.  Or
perhaps you decide that it would be better to create a G-exp or package
for the script.

For running arbitrary scripts we have 'guix environment': perhaps it
would make sense to add /usr/bin/env to `guix environment --container`?
