[Rd] Package issue

[Terry Therneau]

 I've converted the bdsmatrix package (used by coxme) to the newer style of
S4, and uploaded it.  It is in the pkg directory of survival, on r-forge.
I'm stuck on something that is almost certainly a namespace issue. I've 
borrowed liberally from Matrix (a big help) and read the documentation, and
just upgraded to 2.8.1 - but still stuck.

  All the tests work when I run them "by hand", but tests/gchol2.R fails 
when run from R CMD check.  The failure looks a lot like a method for
    setMethod('diag', 'gchol')
is not being found.  

 The NAMESPACE file exports diag, along with several other methods that
do work.  Any help would be appreciated.
