Hello, I placed this code in a baseline of my package: spec project: 'VoyageMongo' with: [ spec className: #ConfigurationOfVoyageMongo; version: #stable; repository: 'github://pharo-nosql/voyage/mc'; loads: #('mongo tests') ]. Unfortunately, when I load my Package from Pharo6 on MacOS Sierra I get the following error: Error: Unsupported OS platform The first lines of the stack are: BaselineOfPunQLite(Object) error: BaselineOfPunQLite platformLibraryName BaselineOfPunQLite preLoad MetacelloMCVersionpec(MetacelloSpec) doItBlock: In detail: platformLibraryName " Answer a name for the compiled version of the library " Smalltalk os isUnix ifTrue: [ ^ 'unqlite.so' ]. Smalltalk os isWin32 ifTrue: [ ^ 'unqlite.dll' ]. Smalltalk os isMacOSX ifTrue: [ ^ 'unqlite.dylib' ]. self error: 'Unsupported OS platformâ With Pharo6 on MacOsSierra, « Smalltalk os isMacOSX » return « false ». But « Smalltalk os isMacOS » return « true ». What can I do? I just need to load Voyage with the configuration of my package ? Thanks.
