Did you run both autogen and configure? If so, please post the config.log.

>It is in /opt/local/include. 

If /opt/local/include/ on Mac OS X is the same as /usr/include/ on Linux then
I'd expect the uchar.h header to be in /opt/local/include/unicode/. Of course,
it's possible that it isn't there because, for example, icu-uc hasn't been
installed.

>What do I need to do to get this to be found?

Let's first find out if, in fact, the header is there as well as why configure
isn't protecting you from the problem.
