> building "pkgsrc/x11/xcursor" fails under Mac OS X Leopard during

This package should be removed sometime. Its source is not maintained.

I don't answer your questions specifically, but just want to mention this 
covers a mix of deprecated xlibs, modular x.org, and native X and 
non-existent builtin.mk files.

Do you need this x11/xcursor? Does your native X already provide a better 
libXcursor?

I think this package should fail before it gets to that configure 
problem.
