Was the semistatic binary built on a modern machine, and you're not trying
to use it on an older machine?  If so, what probably happened is that
configure has detected getaddrinfo is available and has used it for name
resolution in the netxx code.  However, getaddrinfo doesn't work well with
statically linked binaries--in fact, the linker will warn you about this:

% cc -static getaddrinfo.c
/tmp/cclZTOsu.o: In function `main':
getaddrinfo.c:(.text+0x84): warning: Using 'getaddrinfo' in statically
linked applications requires at runtime the shared libraries from the glibc
version used for linking

...which means that the statically linked binary will work on the machine I
built it on, and any machine that happens to have a recent enough glibc, but
will fail with address resolution errors on machines with a glibc that is
too old.

This looks like a genuine bug.  It's probably something like us failing to
handle the fact that IPv6 is not available at runtime.  It'd be worth
opening a bug in the BTS about this.
