golang doesn't statically link everything by default (anymore?), this is from FreeBSD:

    $ ls -l axe
    -rwxr-xr-x  1 root wheel 12830781 Mar 12 22:38 axe*
    
    $ ldd axe
    axe:
        libthr.so.3 => /lib/libthr.so.3 (0xe2e74a1d000)
        libc.so.7 => /lib/libc.so.7 (0xe2e74c27000)
        libsys.so.7 => /lib/libsys.so.7 (0xe2e75de6000)
        [vdso] (0xe2e7366b000)

I know off topic, but is that mostly coming from the Go runtime (how large is that about?)

The excessive size of Go binaries is a common complain. I last recall seeing a related discussion on Lobsters [1]. Who knows, maybe the binary could be shrunk a bit? IMHO 12mb binary size is not that big of a deal.
