[Pharo-project] Alien + MacVM + plugin/primitive error

Hi Guys, Jannik pointed an interesting problem. If I load Alien in both 1.1 or 1.2. Gofer it squeaksource: 'MetacelloRepository' ; package: 'ConfigurationOfAlien'; load. ((Smalltalk globals at: #ConfigurationOfAlien) project version: 'Pharo 1.1') load: {'All'. 'MacOSX'} - with the MacVM 4.2.5beta1U => 40 tests green (it works) - with the MacVM 5.7.4 => 20 tests green and 20 errors (can't call a simple external function) it seems that the I32ABI plugin is not loaded correctly. AlienLibrary>>primLoadLibrary: 'IA32ABI' failed. Any clue to make it work in the MacVM 5.7.4? #Luc
