Why the exclamation mark? Note profile.glm is not actually in package:MASS
(sic). Try looking for it:
A single object matching 'profile.glm' was found
It was found in the following places
registered S3 method for profile from namespace MASS

The accurate description is the intended behaviour.

It isn't in the package ....
There is currently no way to remove registered S3 methods like confint.glm
in an R session. Nor is there likely to be in the near future,
General comment: R has changed quite a lot recently, and older
preconceptions do need to be checked against current information.
The article `Name Space Management for R' in R-news 2003/1 may help
(although it may tell you mor ethan you want to know).
