There are (at least) four ways of doing it.

Add /opt/GNUStep/System/Libraries/ix86/linux-gnu to your /etc/ld.so.conf,
or use opentool,
or do a make install to install your program in the standard GNUstep 
location,
or set up your environment as instructed in the HOWTO

The opentool script will set up library paths and run your tool.

Installing a program will create a shell script with the same name, 
which will
set up libraries and run the binary.

Doing '. /opt/GNUstep/System/Makefiles/GNUstep.sh' will set up 
LD_LIBRARY_PATH
with the correct libraries.

Yep ...
Just remember to do '. /opt/GNUstep/System/Makefiles/GNUstep.sh' before 
you start.... put it
in your .bashrc or somewhere like that.

The makefiles in base/Tools are pretty straightforward examples.
