libsdl_pango: fix dependencies

[mojca (Mojca Miklavec)]

When installing some ports, libsdl_pango from the buildbot was broken as it linked to no longer existing /opt/local/lib/libffi.5.dylib (libffi provides /opt/local/lib/libffi.6.dylib).

Here's the full list:

I don't have a clean delete_la_files installation, so I don't know how to reliably tell which dependencies to add without some further testing.

But these three don't seem sufficient:

depends_lib         port:libsdl \
                    port:fontconfig \
                    path:lib/pkgconfig/pango.pc:pango

I added libffi in r122702, but I would like to ask for help with this issue.

[mojca (Mojca Miklavec)]

Oh, great. The port doesn't even compile any longer.

SDL_Pango.c:661:1: error: conflicting types for 'SDLPango_CopyFTBitmapToSurface'

And where it did build (Snow Leopard), it isn’t linked with libffi. That was probably just leftover overlinking.
