With a clean install of the "Haskell Platform". (OS X Snow-Leopard & Platform 2010.1.0.1), doing this causes simple sequence causes very weird cabal install
behaviour:
$ cabal install time
$ cabal install random
$ ghc-pkg list random
/Library/Frameworks/GHC.framework/Versions/612/usr/lib/ghc-6.12.1/package.conf.d
random-1.0.0.2
/Users/yairc/.ghc/i386-darwin-6.12.1/package.conf.d
random-1.0.0.2
random-1.0.0.2
is installed twice in my system. and now doing cabal install random
reinstalls random-1.0.0.2
every time.
Looks like random
depends on time
, and cabal wants to reinstall it after there's a new version of time
available? And because of two random-1.0.0.2
cabal is confused and always thinks it's not up to date because it's looking at the first one?
ghc-pkg check
finds no errors.
