gorm compile error

Hi,

I am trying to compile gorm from svn and the the following compile error:

Making all for app Gorm...
 Compiling file Gorm.m ...
 Compiling file main.m ...
 Linking app Gorm ...
GormCore/./obj/libGormCore.so: undefined reference to `class_nextMethodList'
collect2: ld returned 1 exit status
make[2]: *** [Gorm.app/./Gorm] Error 1
make[1]: *** [internal-app-run-compile-submake] Error 2
make: *** [Gorm.all.app.variables] Error 2

Does someone know what's wrong here? What do I have to do to fix this?

Thanks,
Michael
