Only  that  IIRC,  Apache  cleans  the environment  and  set  its  own
variables for the CGI.

Since speed is important, I would suggest either:

      - to set  the GNUSTEP variables  directly in the  wrapper script
        instead of running GNUstep.sh each time:

        echo '#!/bin/sh' > wrapper
        . /opt/GNUstep/System/Makefiles/GNUstep.sh
        env | grep GNUSTEP_ | sed -e 's/^/export /' >> wrapper
        echo 'Adaptor' >> wrapper
        chmod 755 wrapper

      - or, to be  even more speedy, to set  the environment variables
        in main()  before initializing GNUstep  from the tool.  (If it
        was an application, you'd have to start it directly naming the
        binary instead of the script in the application package).
