NSProcessInfo not found using 'defaults'

[Chris Apers]

Hi,

Following the install process at :
http://gnustep.made-it.com/BuildGuide/index.html

I tried to set time zone and language after BASE build using 

$ defaults write NSGlobalDomain "Local Time Zone" Europe/Paris
objc runtime: cannot find class NSProcessInfo
Aborted (core dumped)

As you can see there is an error executing this command.
Any idea how to fix this ?

Thanks
Chris
