Hi, I have not tried using libdispatch. However, do you need to manually force GNUstep to link with it? I'm especially concerned about the need to specify linking with libobjc.
Perhaps this can help? http://dl.dropbox.com/u/8559454/GNUstep%20libobjc2%20on%20Ubuntu.sh I doubt it'll reveal anything you don't already know, but this works for me on cleanly installed Ubuntu 10.04. It's based on Etoile's INSTALL file. It's fairly lengthy, since clang is compiled as well. This script is to be run in the home folder and it installs clang into your home folder's llvm/Release+Asserts/bin (to avoid conflicting with system-wide clang you may have). Post-compile, I also added ~/llvm/Release+Asserts/bin into PATH, and I sourced GNUstep.sh to make compiling easier.
