reproducibility

Hi,

I've noticed that a derivation is a function of the order of the
inputs. As an example, the following two input orders give rise to two
distinct derivations:

A)

    (inputs
     `(("texlive" ,texlive)
       ("texinfo" ,texinfo)
       ("m4" ,m4)
       ("libx11" ,libx11))

B)
    (inputs
     `(("texinfo" ,texinfo)
       ("texlive" ,texlive)
       ("m4" ,m4)
       ("libx11" ,libx11))

Is this intentional?

Regards,
Fede
