    gprofng: fix bug 29351 - Move dynamic loading of modules to a later stage

            * gp-display-html/gp-display-html.in: the dynamic loading of
            modules occurred too early, resulting in the generation of the
            man page to fail in case a module is missing; the loading part is
            now done somewhat later in the execution to avoid this problem.
