Description Ozkan Sezer 2017-10-22 09:05:48 UTC 
The attached patch makes sure that we are building against
a recent-enough libmpg123:  mpg123_replace_reader_handle()
requires MPG123_API_VERSION >= 24.

We actually want to catch this during configure rather than as an error at build time.

I've implemented that here:

Thanks!
