Indeed.

However, as Uwe properly pointed out in a related E-mail,
there is a bug -- still not in R , and hence not for R-bugs !! ---
in the DESCRIPTION file of newer versions of 'cluster':

You shouldn't have been able to install the current version of
the package 'cluster' with your ancient version of R, since
cluster effectively requires R version >= 2.2.1
(because earlier versions of R had a bug in their registration
 of Fortran symbols).

Hence, if you want to continue using your outdated version of R,
you should really use the old version cluster that was part of
your version of R...
