Oh, yes, well spotted. There’s obviously is mismatch of the runtime system 
versions. The names that the loader flags as missing make it look like the 
ProjectCenter framework was compiled for a 1.x version of the GNUstep runtime 
system. The 2.x versions use different names for the class objects (essentially 
replacing the prefix __objc_class_name_ by ._OBJC_CLASS_), so mixing libraries 
or programs compiled for an older version of the runtime with those for the 
current version is not possible.

Now I would expect that the FreeBSD packages don’t mix incompatible versions, 
so maybe uninstalling and then reinstalling all GNUstep related packages would 
get you straight again. Presumably the FreeBSD packages system has a command to 
recursively update all your installed packages, but as I said I’m not really an 
expert on this.
