A few weeks ago I accidentally turned on a cvs lock for 
VTKConfig.cmake.in and made a change to it, which caused all checkouts 
of it to get a read-only copy.  Then CMake configured the file to the 
build tree as VTKConfig.cmake with read-only permissions.  The next day 
I removed the lock but it was too late to help those who had already 
updated and configured.  CMake 2.0 has a bug in that it will not 
overwrite a read-only destination with CONFIGURE_FILE.  This did not 
really cause any problems until changes were made that caused 
VTKConfig.cmake to change and therefore need to be overwritten.  Your 
changes probably triggered this.

I've fixed DASH3 by manually fixing the permissions.  The problem should 
go away now.  The CMake bug has been fixed in CVS too.
