Compiling the CVS version is no real problem, but it tends to be slightly less stable than the distro, so I tend to prefer to stick with the distro for production work. Well, I guess I'll have to update my source directory and bootstrap it. > I recommend running > ./configure with an option like -prefix /usr/local/stow/ocaml-cvs/ if > you want to keep it alongside Ocaml 3.04 (if you do not know "stow", > have a look to it, it is interesting). Reading your Makefile I had thought that stow was some strange name or acronym for a project you might be working on. Now you teach it is a package manager. Ok, I'll try it out. > The compile directory of the FFTW interface is where the library is > expected to stay. I may try to add a "make install" if you need it. Of course, I would appreciate greatly. But I do not wish to hassle you more than I have already.

This is definitely worth the effort. But, it is such a pity that nothing can be done to rendere the installation painless until the new release is out. Thank you very much.
