in more detail, build scrips routinely use `pwd` to figure out the current directory. Now, watch this (on OSX):
nash:~ dima$ cd desktop nash:desktop dima$ pwd /Users/dima/desktop nash:desktop dima$ cd nash:~ dima$ cd Desktop nash:Desktop dima$ pwd /Users/dima/Desktop No wonder these "slightly wrong" paths get into configurations, and then some tools, which are case-sensitive, choke on them...
