This is counter-intuitive but expected.  First of all, the profile is
built by running a Guile program, so Guile needs to be available if it=E2=
=80=99s
not already there.

Secondly, when the profile is built, a number of =E2=80=9Cprofile hooks=E2=
=80=9D are
run.  We can see them above: gtk-icon-themes builds a registry of the
installed GTK+ themes (which requires GTK+), info-dir builds the Info
documentation directory (which requires Texinfo), and so on.

Most of these hooks do not pull additional dependencies (for instance,
the GTK+ hook uses the GTK+ that you already have), but some do (the
Info hooks pulls in Texinfo).

HTH!
