Comment (by barracuda156):

 Replying to [comment:2 ryandesign]:
 > Yes, this problem affects Mountain Lion and earlier. I guess
 `TCP_KEEPINTVL` and `TCP_KEEPCNT ` aren't declared by the system headers
 on those OS versions. I haven't investigated whether upstream has already
 fixed this (we are not using the latest version yet because that would
 require switching to the meson build system and I didn't feel like dealing
 with that yet) or, if not, what the solution would be.

 Yeah, these appear from 10.9 onwards:

 #if !defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE)
 …
 #define TCP_KEEPINTVL           0x101   /* interval between keepalives */
 #define TCP_KEEPCNT             0x102   /* number of keepalives before
 close */
