install.packages() does indeed have code to check for dependencies of 
dependencies.  I got the message

also installing the dependencies 'acepack', 'scatterplot3d', 'quadprog', 
'fBasics', 'Hmisc', 'mlbench', 'randomForest', 'SparseM', 'xtable', 'oz', 
'leaps', 'dynlm', 'e1071', 'tseries', 'chron', 'fCalendar', 'its', 'DAAG', 
'abind', 'car', 'effects', 'lmtest', 'multcomp', 'mvtnorm', 'relimp', 
'sandwich', 'strucchange', 'zoo'

The problem is the ordering.  Rcmdr does have mvtnorm in the 'Suggests' 
list, and has it after 'multcomp', and install.packages does not check 
that the Suggests list does not have inter-dependencies.

So we do `do something smarter', but not smart enough.
