Hi,

I tried reconfiguring my system recently using pre-inst-env, using
commit 08861d259b453442c38fe93477bc62d2080b1442.  I got this error:

$ sudo ./pre-inst-env guix system --fallback reconfigure ~/config.scm

I expected pre-inst-env to make all the necessary dependencies
available.  I was surprised that the guix command was unable to find
(gcrypt hash), even though I thought pre-inst-env would make it
available.

Is this a bug, or am I doing something wrong?
