 "`-shared`" is a flag that is used on other UNIX systems, but on Mac OS X,
 "`-dynamiclib`" is used instead. Recent versions of Mac OS X allow
 "`-shared`" as a synonym for "`-dynamiclib`", but Tiger is not recent
 enough for that. The attached patch fixes this.

 However, the dynamic library that's being built here doesn't actually end
 up getting installed -- and pianobar works fine without it. So I'm unsure
 why the dynamic library is being built at all, and maybe a better patch
 would be one that disables building the dynamic library.
