It's made postgres dependent on a version of libicu that it hasn't requested to be installed. It's possible that you could work around this by manually installing that libicu version first. But there could be other version-skew problems lurking behind this one, so prodding the formula maintainer seems to be the easiest path. regards, tom lane
