make compilation succeed on macosx; this will still run macs out of disk space. Also, it disables a number of binaries that probably should be supported on macs.

I found a segfault bug this morning, but cannot reproduce. Could be a heisenbug, or could have been a hardware fault (gojira repeatedly kernel paniced, then both problems went away...)
