Surely the install script can be made smart enough to make [n] the default on Mac OS X?
Even if the test is done in very general terms - i.e. if it were written to look for a case-insensitive filesystem instead of for a specific OS - you'd still need such a system to verify the test. In practical terms, that means testing it on a Mac - I don't know of any other UNIX that uses a case-insensitive filesystem.
Looking at the list of named in the LWP docs, I don't recall seeing any of them post here. My guess is that none of the module maintainers uses a Mac. So, they did the best they could; they made it configurable as a courtesy to Mac users, but used a default that's appropriate for the majority.
