Hi! I tried to built a Pharo-dev from a 11229. I executed the script given in a Pharo distribution: -=-=-=-=-=-=-=-=-=-=-=-= Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfPharo'; load. ((Smalltalk at: #ConfigurationOfPharo) project version: '1.0- rc2.10508') load. Gofer new squeaksource: 'ImageForDevelopers'; package: 'ImageForDevelopers-pharo'; load. (Smalltalk classNamed: #DEVImageCreator) default install. -=-=-=-=-=-=-=-=-=-=-=-= But I get an error raised by MetacelloPackageSpec>>instVarNames:put: apparently some reflective operations try to access a non-existing variable. I know that Pharo is meant to be built from a stable core. But I would like to benefit from the snappy interface and the nice menu. Anyone tried ?
