FWIW the build succeeds if you force it past the failing mmap() configure 
test.

I fixed this by adding the output of "hostname" to /etc/hosts. Eg:
127.0.0.1               localhost.localdomain localhost jet

Yeah, it's protected by that, but looking at the code it relies on the output 
of socketpair():

#ifndef NO_SOCKETPAIR
        status = socketpair(AF_UNIX, SOCK_STREAM, 0, pipefd);   /* create 
stream sockets */
#endif
(...)
        status = read_write_close(i64, "Stream Pipe", pipefd[0], 
pipefd[1]);    /* do the test */
