HFS+ is not case sensitive, it's case "preserving" (by default).

Whatever case you use when you create the file/directory is kept.

When you want to *refer* to it, you can use *any* case you want.

touch toto
ls -l Toto

should exhibit that (I can't try it myself because I activated
the case *sensitive* option when I installed Tiger).

Historically I think the idea was that the user didn't have to
remember the caps it has used (studly caps rings a bell ? :).

The drawback is that you can't have Makefile and makefile in the
same directory (main reason I get rid of that preserving
sillyness as soon as I could).

You already have an option to HFS+ to make it (at format time)
case sensitive.

But be aware that some third-party applications can break (if
they refer to an internal file by 'resource.mine' to a file named
'Resource.Mine' on the filesystem).

    Bob> Second question: How can I work around this issue?

Have a look at:

    Bob> Scenerio: A lower case directory was renamed to an upper case directory.

    Bob> Directory '/path/project/stubby', it was renamed to '/path/project/Stubby'

    Bob> $ bzr status
    Bob> removed:
    Bob>    stubby/
    Bob>    stubby/GPL.txt

    Bob> $ bzr commit
    Bob> Commiting revision 153 to "/path/project/".
    Bob> bzr ERROR: no changes to commit. use --unchanged to commit anyhow

You can try to work around with bzr mv, but I can't test it
itself so I can't propose a verified solution.

    Bob> $ ls -d Stubby
    Bob> Stubby/

    Bob> $ ls -d stubby
    Bob> stubby/

    Bob> Yet(!)

    Bob> $ ls -a | grep -i stubby
    Bob> Stubby

Yes, *that's* case preserving :)

And just for fun what is the ouput of:

  ls -d *tubby
