This is where you went wrong ... you can't really build code trying to use a 
compiler directly because there are various options, include directories, and 
libraries which need to be used.
You should use gnustep-make to automate the build process and fill in all those 
options for you.

See http://www.gnustep.it/nicola/Tutorials/WritingMakefiles/index.html for a 
good starting point.
