ffiCall:module: is UFFI, then Pharo 5.0 exclusive.

Hi ,

Thanks Esteban, I have install pharo 5 and another issue appear when working with it. when i create a class and i try to inspect the class am having the following issue:
Here is my class:
Object subclass: #InterfaceDev
        instanceVariableNames: 'errbuf'
        classVariableNames: ''
        package: 'Network-sniffer

when I inspect it i have:

Object subclass: #InterfaceDev
        instanceVariableNames: 'errbuf'
        classVariableNames: ''
         Variable or expression expected ->package: 'Network-sniffer'
With this i cannot initialize my instant variable "errbuf"

Best Regards
