[Pharo-project] How to force Metacello to use the package cache?

Hi guys I'm trying to work on Moose and I get 200 package to download during my experiments ~ 30 min at minimum Does anybody have an idea how to make sure metacello use the package cache? I started to comment cacheGofer cacheGofer == nil ifTrue: [ "don't use a caching Gofer here, since we expect the contents to change during a fetch operation" cacheGofer := Gofer new. >>>> cacheGofer disablePackageCache. cacheGofer repository: self cacheRepository. ]. ^ cacheGofer But no success so far. Still looking around Stef
