I don't know much about the program options library or the OS X locale
tools. But I can help a little with your questions about building
under darwin.

First of all, it is generally a good idea to stick with the gcc
provided by Apple with the Xcode distribution. Even though the
compiler is named gcc, you'll want to use the darwin toolset. It looks
like this is what you've been doing. The toolset is not confused about
what version of OS X your are running. The macosx-version-10.4 is
indicating that 10.4 is the minimum version of OS X on which your
built artifacts will run. At this point in time, it remains a good
default. If you tell bjam to use macosx-version=10.5 you will be
perhaps be abel to take advantage of 10.5-only features, but the
resulting executables will not run under earlier OS versions. You can
read more about this in Apple's documentation on the
-mmacosx-version-min compiler option. See also the related -isysroot

Hope this helps,
