subversion isn't sure how to deal with colliding filenames from a 
case-sensitive repository being checked out onto a case-insensitive client. 
This is arguably a bug in the FreeBSD repository since it is desirable for 
people to be able to check out our tree on Mac OS X, etc.  Interestingly, it 
also triggers real bugs in the svn client -- when I tried to clean up after 
the aborted checkout on my Mac OS X notebook, I got:

robert_at_cinnamon:~/freebsd% svn cleanup head/
svn: In directory 'head/tools/regression/usr.bin/pkill'
svn: Error processing command 'modify-wcprop' in 
'head/tools/regression/usr.bin/pkill'
svn: 'head/tools/regression/usr.bin/pkill/pkill-U.t' is not under version 
control

rm -Rf on the pkill subtree appeared to help :-).  I've corrected that 
instances of name collisions and am now attempting to check out the remainder 
of the tree, and will follow up if I have to correct further problems.

In general, you should be able to create a disk image on Mac OS X that *is* 
case-sensitive, using Disk Utility, and check out there without a problem. 
Currently we do not support cross-build form Mac OS X, so most people 
developing on Mac OS X are using VMWare Fusion or some other 
emulator/virtualization package.
