Is this on a (more or less) recent Debian system? I have seen similar errors 
for another project when upgrading to Ubunutu 12.04. In the end it turned out 
that these errors were due to a linker change, which no longer automatically 
re-exports symbols from shared objects/libraries that are defined in other 
libraries. Adding a few more -l flags to ADDITIONAL_TOOL_LIBS solved the 
problem for me. Since I'm not using (and have never used) GDL2, you'll have to 
find out the correct makefile variables and libraries yourself.
