I've worked out what happened:  there was a build of R-patched which 
overwrote the release, because it happened before the VERSION file had 
been updated to include "Patched".  I don't upload md5sum.txt in the 
R-patched or R-devel scripts, so that's why you detected the difference.

To confirm this, you could check the NEWS file:  it contained entries 
for 2.6.2 Patched, as well as the 2.6.2 entries.  As far as I know it's 
perfectly safe to use.
