Looking at PSPP, I see the following regarding its library
dependencies:

        * Copyright on GSL is not owned by the FSF, but it
          appears to all be under a "GPLv2 or later license".

        * libiconv, readline, plotutils are owned by FSF and
          under "GPLv2 or later license".

        * libiconv, readline, plotutils are owned by FSF and
          under "LGPLv2 or later license".

        * ncurses is owned by FSF and under an MIT-style license
          (!).

        * Copyright on libglade is not owned by the FSF, but it
          appears to all be under a "LGPLv2 or later license".

As for the code in lib/, I see the following:

        * gsl-extras (written by Jason) is owned by FSF and under
          GPLv3 or later.

        * gtksheet (hacked on by John) is owned by FSF and under
          LGPLv2.1 or later.

        * linreg (written by Jason) is owned by FSF and under
          GPLv2 or later.

My conclusion is that we can relicense under GPLv3 without
needing any other change.
