[Haskell-cafe] package cache being out of date

[Wolfgang Jeltsch]

Hi,

I have a freshly installed Haskell Platform 2010.2.0.0 on Windows 7.
When I run ghc-pkg list, I get the following message (besides the
expected package info):

    WARNING: cache is out of date: C:/Program Files (x86)/Haskell
    Platform/2010.2.0.0\lib\package.conf.d\package.cache
     use 'ghc-pkg recache' to fix.

What does this mean? Is this harmful?

(In principal, I could just run ghc-pkg recache, but the installation is
replicated on about 20 machines, and I don’t have admin rights on
these.)

Best wishes,
Wolfgang
