Well, after the arguments setting the variables, portable env really
only takes a command line with arguments, not something that is passed
to the shell again. You could work around this by constructing
something like
/usr/bin/env var=val ... sh -c 'script ...'
>> With the || and ;, are the () really unnecessary?
Well, neither the () nor the || nor ; really belong in a command-line
that is not interpreted by a shell.
