here is how I do it on OpenBSD:
1. install libobjc2 using the Makefile, not the GNUmakefile, which will end up
in /usr/local
2. install gnustep-make, there I use LDFLAGS='-L/usr/local/lib'
CPPFLAGS='-I/usr/local/include/' in the environment when running configure
3. install gnustep-base and others. at that time, gnustep-make should have
picked up the CPPFLAGS and LDFLAGS from its installation time
and should use them.
