420	cabal-install upgrade optionally ignore packages that want a higher base?	jimburton		"If I try to upgrade all packages it fails because syb wants a newer base:


{{{
$ cabal upgrade
Resolving dependencies...
cabal: cannot configure syb-0.1.0.0. It requires base >=4.0
There is no available version of base that satisfies >=4.0
}}}

I don't want to upgrade GHC (in fact I can't right now) but I presume that there are other packages that could upgrade. Rather than run `cabal install' on them one by one, what about upgrading everything that is upgradeable, i.e. happy with the current base? There is a (misleading) analogy to the way apt treats releases -- it won't tell me ""Can't upgrade because you're using the wrong release"", but releases are self-contained and upgrades take place within that context...but obviously different because there you have different package lists for different releases...
