Mac build fun

[Michael McMahon]

Are you building on a remote filesystem like NFS? Those .DS_Store files 
get created by the finder
and can cause problems on remote filesystems where they become visible 
to other software.

There is a way to disable creation of .DS_Store on remote filesystems 
documented at
