[R] issue with update.packages(), library 'utils'

[Iago]

Dear all,

What is the conclusion of this discussion? If the issue is due

|to the 'Last modified' / .builtData that apparently changes on the 
repository every day, although the version numbers of packages are not 
changed |

should then be solved on CRAN side? Are CRAN maintainers going to do 
that? Or should the issue be raised to R-devel in order to be solved on 
the ‘utils’ library side? Or should R users get used to this issue 
indefinitely?

Thanks!

Best,

Iago
