 I decided to rename `py-python-poppler-qt4` and to use PyPI as source
 instead of GitHub (see the thread starting with
 [https://lists.macosforge.org/pipermail/macports-
 dev/2015-January/029522.html this message]).[[BR]]
 I had to remove the entry about `py-python-poppler-qt4` from `py-
 graveyard` because MacPorts cannot handle "replaced_by chains" (see the
 thread starting with [https://lists.macosforge.org/pipermail/macports-
 dev/2015-January/029525.html this message]).

 The changes are meant to be applied all at once:
 * the Portfile for the **new** port `py-poppler-qt4` is `Portfile-py-
 poppler-qt4`;
 * the `py-python-poppler-qt4` Portfile must be **replaced** by `Portfile-
 py-python-poppler-qt4`;
 * the `frescobaldi` Portfile must be **patched** with `Portfile-
 frescobaldi.diff`;
 * the `py-graveyard` Portfile must be **patched** with `Portfile-py-
 graveyard.diff`.
