Most often than not, but I know of cases where the headers for the
current version of a library are put directly under /usr/include,
whereas the older versions are in subdirectories of /usr/include and
require pkg-config, and therefore if pkg-config is not used, the CFFI
code will be compiled against the wrong(newer) library. IIRC, this is
the case with BerkeleyDB and Postgres's libpq on some distributions.
