As I understand it, cabal doesn't currently deal with updates and  
dependency checking because it's too easy to
get into "diamond dependency" issues.  (Package A updated, package B's deps  
specify old version, package C's
deps either specify new version or default version, package D tries to use  
packages B and C => bad things
happen; the only way to prevent this "automatically" would be to refuse to  
allow package A to be updated at all,
and if package D is installed later it must refuse to allow the install  
until someone fixes the dependency conflict
manually.)
