I took a slightly different approach in commit c046815 (and also not
passing “impureEnvVars” by default since that would lead to a full
rebuild.)

With commit 0d88313, $http_proxy is honored, but note that it’s the
$http_proxy value in the daemon’s environment that is used, not in the
client’s environment.

We will need to update the bootstrap Guile, but that won’t happen until
a later full-rebuild cycle.

You should be able to use substitutes as a workaround in the meantime.
How does that sound?

Thank you!
