Please use a meaningful subject line: yours was far too vague.

That's a problem with the package, not R-devel: it should not be calling a
method.  Do note the USER-VISIBLE CHANGES in the NEWS file:

    o   Namespaces can now be defined for packages other than `base':
        see `Writing R Extensions'.  This hides some internal objects
        and changes the search path from objects in a namespace.  All
        the base packages (except methods and tcltk) have namespaces,
        as well as the recommended packages `KernSmooth', `MASS',
        `boot', `class', `nnet', `rpart' and `spatial'.

predict.loess is no longer user-visible. Calling predict() will work with
correctly-written code.

There are still a few (three I think) such problems in the CRAN packages, 
and you can't expect all packages to have been updated for a version that 
is not even feature-frozen as yet.
