Hello, Sorry I asked this question before .. say I want to install package A that depends on package B, C, D but maybe B and D are not installed on my machine. Basically I want to "fault in" (i.e. install automatically) in B and D with "no fuss no muss". ??? In reality I would like to get my laptop which is running Ubuntu totally "faulted up" with all Haskell packages ... ;^) Regards, Vasili
