[Rd] Dependencies on recommended packages

[Uwe Ligges]

Does it still happen with R-2.15.0 patched? Maybe an old version of 
Matrix in a library that is first in the search path? Unfortunately 
glmnet does not import from Matrix and search path issues are likely to 
happen. This needs to be sorted out on R-forge , I think.

Best,
Uwe Ligges
