The question is, why do you want to do that?
And even better question, what platform do you are on, which version of OpenBSD?
You are missing important information ;)

And why don't you leverage the ports infrastrucutre, its all there, and 
likely only a few lines change in the ports Makefiles.

With regard to the libobjc, do you have thought about installing
ports/x11/gnustep/libobjc1, or have ports/x11/gnustep/libobjc2 installed?

cheers,
Sebastian
