Are you thinking of UFS, because I am running HFS+ and I still get python.exe since it's case-preserving.

No, not UFS. Since at least 10.4, OS X has supported the creation of at least four variants of HFS+ via Disk Utility.app or disktutil(8). The 10.6 version of diskutil added a handy way to list all available file systems:

$ diskutil listFileSystems Formattable filesystems [...]

PERSONALITY USER VISIBLE NAME

[...] HFS+ Mac OS Extended
Case-sensitive HFS+ Mac OS Extended (Case-sensitive)

(or) hfsx Case-sensitive Journaled HFS+ Mac OS Extended (Case-sensitive, Journaled)
(or) jhfsx Journaled HFS+ Mac OS Extended (Journaled)

(or) jhfs+

These days, one of the latter two is used to format the primary file system where OS X resides: I believe journaled is a requirement from at least 10.5 on, case-sensitive is optional. I've been using "jhfsx" for my primary development machine since 10.5 was released a few years ago.
Since it is a file system type, AFAIK it is necessary to re-initialize the partition and reload files on it.

Regardless, I will add a note about the case-sensitivity.

Thanks!
