LibSDL_Mixer - static lib is linked to dynamic libs

I have to apologize, I seem to have had a bad case of thinking :)

With the ./configure options
--disable-music-mp3-shared \
--disable-music-ogg-shared \

libsdl_mixer gets correctly build, meaning the static lib is not linked against the dynamic libs of its dependencies. So wherever you want to link statically to sdl_mixer you need to add the static libs of sdl_mixer's dependencies.
As dynamic linking still works with these ./configure options, I *think* it should be safe to add these options to the portfile.
I'll add this to the ticket I posted.

Take care,

After messing around with the hurdles of building programs static, I had been almost successful, only to be plagued by libsdl_mixer. It's static file is dynamic linked to other libs (libvorbis, libogg, libflac) which IMHO defeats the purpose of having a static lib.
>>>> That sounds like a valid complaint. For the benefit of those of us not familiar, how do you determine that the static lib is dynamically linked to other libs?
>>> I have no real idea how to tell that. otool does not print out any dylib, though when I look at libsdl_mixer.a directly, I see the references to the dylib files. Also it was clear when Exult was running in the "Activity" that the dylibs were used, even though Exult doesn't link them and libsdl_mixer.a was linked in the exult binary.

>>> Yes, building directly from source was not successful as well, and I couldn't "hack" the makefile similar to how I "hacked" the exult makefile to link to the static libs :(
>>> So, this is most likely an upstream problem.

one day, walking, I awaken, 
amazed to see where I have come, 
where I'm going, where I'm from. 
This is not the path I thought. 
This is not the place I sought. 
This is not he dream I bought, 
just a fever of fate I caught."
