make: *** [check] Error 1

Note: the standard Mac OS X file system is case insensitive. It is in general not possible to directly mv foo to Foo. One has to move foo to foo.tmp and then move foo.tmp to Foo or use some other work around. I don't know how the test is done but it seems more likely that one file is being recognised twice than that "both files exist".

I'm wondering if this test should at least be flagged as an expected failure on case insensitive file systems.

Actually, I see it is meant to work around this, but apparently isn't...

I didn't noticed the bug earlier, bugs this has been fixed on bzr.dev
