The recv() system call and MSG_PEEKconstanct are declared in sys/socket.h

But your temp.config says:

checking sys/socket.h usability... no
checking sys/socket.h presence... no
checking for sys/socket.h... no

So the configure script thinks that sys/socket.h doesn't exist on your system:

There's something wrong with your system or with the configure script.  Given 
that sys/config.h is pretty basic, it's probably there, which makes your clang 
compiler the most likely faulty component ... try configuring/building using 
the standard compiler instead.
