 Summary of the bug: On OS X 10.7, using

 This set of flags was working great until my last build on Oct 15.

 ld: symbol(s) not found for architecture x86_64
 clang: error: linker command failed with exit code 1 (use -v to see
 ERROR: libcdio not found

 nm says that symbol is present in /sw/lib/libcdio_cdda.0.0.3.dylib.
 However -lcdio_cdda (or any other of the the cdio lib flags) is not being
 added to the linker command --> undefined symbol error.

 Git bisect points to 66a1ccd7467ab1913cd8877114c6d4c2588bb12f as the
 culprit.  But towards the end of the bisect run, it starts giving errors
 that configure options are not recognized (Unknown option "--enable-
 libass"), which seems more like the bisect command got confused and left
 the tree in an unstable mode vs it being the actual culprit (though it
 might explain the syntax errors in the original failure).
