This happens if you use the HFS+ file system on Mac OS X: HFS+ is case 
insensitive but case preserving. There have been lengthy discussions about 
this "feature" on several darwin mailing lists. It is there mainly because 
for your grandma "FILE" and "File" are the same ;-). If case sensitify is 
needed (for instance for building some free software projects like 
Xfree86) it is recomended to use a UFS formated disk or if this isn't 
available an UFS formated and mounted disk image (can be created using 
"Disk Copy").
