Installation os osx/darwin is a bit tricky. Here's instructions which maybe could be extracted to a wiki. about text-icu HOT 3 CLOSED

This is not the end of the story. Because then, your program will only work on Macs that have the ICU dylibs in exactly the same locations as you, i.e., they need to have homebrew and they also need to have run brew install icu4c before running your program.

One direction is to modify the dylibs so that they can be distributed together with your executable and placed in the same directory, e.g., as part of an app bundle. There is an SO thread with instructions about how to modify the dylibs. But I haven't been successful at getting that to work yet.

Thanks. That was tricky. I had tried using CPPFLAGS and LDFLAGS and PKG_CONFIG_PATH to no avail.

I just ran into this, agree that it should somehow be documented.
