While I don't like the form in which oliver's remark is expressed, I do
agree that the interface with non-OCaml libraries could be improved. First,
it is strange that not having a C library would fail during the compilation
step (with a non-obvious error message hidden in a sea of text) rather than
the configure step, which is precisely meant to detect this kind of missing
requirements. Second, GODI has a rather nice way to handle external
libraries (they are represented as specific virtualish packages that are
explicitly marked as represented an external dependency, and make it clear
what should be installed for a specific package) and handles configuration
nicely. I would expect the same of OPAM.
