I'm not sure what's wrong here. It works fine for me when I run make in the source directory and I don't have "." in PATH.

That's probably because the configure script didn't find camlp4. Camlp4 is a preprocessor for ocaml, it's needed for compiling this file (viz_style.ml). Camlp4 is built with the ocaml compilers but some package it separately. Try to find and install some ocaml-camlp4 (or camlp4) package and then re-run configure.

The configure script should signal an error when it doesn't find camlp4, I'll change that.
