Here you are installing in the profile ’profile-A’…

…and here, you are listing the packages in the default profile
~/.guix-profile.  Instead you should run,

    machine-B$ guix package -p profile-A -I


Last, as Julien pointed out, it might be possible that on ’Machine-A’
the packages are from various states.  You can give a look at:

    machine-A$ guix package --list-generations

and so, it is possible that the packages you installed do not match the
current state of Guix.  For instance, you could compare:

    machine-A$ guix package --export-channels
    machine-A$ guix pull -f channels

Well, if you did:

    guix pull
    guix install gsl
    guix pull
    guix install pcre
    guix pull
    guix zlib
    etc.

the profile is not composed by only one state therefore it cannot be
replicated.  Only a rough approximation can be made.

Or if you did:

   guix install gsl pcre icu4c etc.
   guix pull

then “guix describe” does not provide the Guix state of the installed
packages.
