When I try to load a Ruby extension that I have checked into ClearCase,  
something weird happens:

./lib/whatever.so: 5: Access is denied. - ./lib/whatever.so  
(LoadError)

If I check out the file, and make it ReadOnly, it still works, so it’s  
not a  
read-write-access-problem. Seems Ruby does some wierd stuff that the  
ClearCase filesystem does not like. Filemon reports a lot of these:

14:13:30 ruby.exe:5804 UNLOCK \<network\_path\_removed\> RANGE  
NOT  
LOCKED Offset: 0 Length: -1

So Ruby requests to OPEN the file, the ClearCase file system for some  
reason  
tries to do an UNLOCK instead of an OPEN. Any help appreciated.
