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.

Wolfgang, Riccardo,
Sorry to keep bothering you for what is probably a mistake I made during the upgrade of FreeBSD. But I upgraded every installed port on the system, causing endless hours and hours of recompilations and installations. and reduced the linker errors in GNUMail and ProjectCenter (maybe other gnustep ports are involved, but I did not try them allyet) to 1.
Can you give any indication where to look for a solution?
Linking ProjectCenter gives:
cc -L/usr/local/lib -fstack-protector-strong -rdynamic -rdynamic -rdynamic -rdynamic -fuse-ld= -pthread -fexceptions -fobjc-runtime=gnustep-2.0 -fblocks -o ProjectCenter.app/./ProjectCenter \

libProjectCenter.so seems to depend on the latest gnustep libraries:
l
$ ldd /usr/ports/devel/projectcenter/work/ProjectCenter-0.6.2/Framework/ProjectCenter.framework/libProjectCenter.so
/usr/ports/devel/projectcenter/work/ProjectCenter-0.6.2/Framework/ProjectCenter.framework/libProjectCenter.so:
/usr/ports/devel/projectcenter/work/ProjectCenter-0.6.2/Framework/ProjectCenter.framework/libProjectCenter.so:
libobjc.so.4.6 => /usr/local/lib/libobjc.so.4.6 (0x8006f0000)
libgnustep-base.so.1.27 => /usr/local/GNUstep/System/Library/Libraries/libgnustep-base.so.1.27 (0x800e00000)
libgnustep-gui.so.0.28 => /usr/local/GNUstep/System/Library/Libraries/libgnustep-gui.so.0.28 (0x801400000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x800725000)
The strange thing is, that symbol seems to be in the libgnustep-gui library:
$ nm /usr/local/GNUstep/System/Library/Libraries/libgnustep-gui.so.0.28 | grep __objc_ivar_offset_NSView._tracking_rects
000000000049f61c d __objc_ivar_offset_NSView._tracking_rects.

Thanks for helping out again,
