Don't think so. In 
libshairplay-139d5ef55564514c31f02dd82cef91236c9ff523/src/lib/dnssd.c 
the macro USE_LIBDL is defined:

#define USE_LIBDL (defined(HAVE_LIBDL) && !defined(__APPLE__))

#if defined(WIN32) || USE_LIBDL
[..]
#else
# include <dns_sd.h>
# define DNSSD_STDCALL
#endif

In this build HAVE_LIBDL is not defined and so is USE_LIBDL not defined. 
Finally, there is no header file dns_sd.h, which breaks the build process.

I guess, the problem is that configure does not find libdl.
