what version of libmpdclient do you have installed?
Recent versions, at least as of end of last year, should have that. I tested 
with at least 2.7 and above.

MPDCon is mainly developed on OpenBSD, which has arc4random in libc. What OS 
you are on?
You may need to install libbsd and I guess libbsd-dev packages, and then tweak 
the environment to
be point the build to find the headers and link against it.
When you have your libmpdclient upgraded, then contact me about the arc4random 
issue privately.
I don't have a Linux box around to be able to test.

cheers,
