How can I get pianobarfly to compile correctly on OS X?

I'm trying to get pianobarfly working on OS X and can't get it to compile correctly.

Selected text from the install document:

Dependencies
------------

gmake
libao               http://www.xiph.org/ao/
libfaad2            http://www.audiocoding.com/downloads.html
AND/OR libmad       http://www.underbit.com/products/mad/
pthreads
libid3tag           http://www.underbit.com/products/mad/
UTF-8 console/locale!



Building
--------

If you have all of the dependencies listed above just type

    make clean && make

NOTE: The above won't work on Mac OS X (Snow Leopard) since c99 targets i386
and cc (gcc4.2) targets x86_64. If you've built supporting libraries
(libao, etc.) using gcc, you'll be unable to link. You can work around
this issue by overriding CFLAGS[1]

    make clean && make CFLAGS="-O2 -DNDEBUG -W64" && make DISABLE_FAAD=1

I think I have all the dependencies, except I'm not sure if I have pthreads or not, and I'm assuming my system default is UTF-8 console/locale!

I have used homebrew to install the dependencies I didn't have, like faad2 and libid3tag, but I haven't been to turn up anything on google about installing pthreads or how to tell if I have that already or not.

Anyhow, when I tr开发者_JS百科y to complile pianobarfly, this is what I get:

This has been resolved within the master and development branch of pianobarfly. Please be aware that there is an issue/patch available for homebrew which resolves a issue where pkg-config was not being generated for id3tag.pc. This patch has not (yet) been integrated into homebrew.

See: https://github.com/mxcl/homebrew/pull/7973

Also see: https://github.com/ghuntley/pianobarfly/issues/3

This is a portability bug in the program you are trying to build: it assumes that strndup() is available, and it isn't.

Fortunately, it's trivial to implement your own strndup replacement, given a description of what it does.

Or you may check fly.c: perhaps replacing strndup with strdup also works.
