Comment (by RJVB):

 I see you're running 10.7.5; how much RAM do you have, and how much free
 space on your boot drive?

 I'm not expecting fluidsynth to be particularly expensive to build but the
 clang compiler can be *very* resource hungry. So if the build fails again
 with the same error you are apparently trying to use more memory than your
 computer can provide. In that case:
 - check how many applications you have running (close browser windows or
 simply quit them for the duration of the build)
 - do *not* do a `port clean` before trying again, so your build process
 continues where
 - add `build.jobs=1 build.post_args=-wk` to the `port install` (or `port
 build`) command. This will ensure that only a single file is built at a
 time, but also that the build will continue as far as possible, regardless
 of errors.

 Personally I would also get ride of the `-pipe` argument to limit the
 number of concurrent build processes even more.
 (I have a lot of working experience with/on underdimensioned system and in
 my experience that makes builds run more smoothly on them. Then again, I
 have the impression that clang does not actually uses distinct processes
 for preprocessor, compiler and assembler.)
