I would recommend also using --enable-shared, because that will make
your loadable .oct files much smaller.

Your system must be missing some things (perhaps because they are part
of a `development' package that was not installed by default).  What
distribution, kernel, compiler, and library versions do you have?

It *should* be easy.  I don't have the latest libraries.  On my
system, dlfcn.h is part of the ldso package.
