GNUstep is not installed yet. Please proceed with installation of GNUstep
as long as you have resolved other errors listed here.

E281 Error
I don't seem to be able to use your Objective-C compiler to produce
working binaries!  Please check your Objective-C compiler installation.
For gcc-3.0.x make sure that your compiler's libgcc_s and libobjc

LD_LIBRARY_PATH or /etc/ld.so.conf.
Please refer to your compiler installation instructions for more help.
