Created attachment 382402 [details, diff] install HTML docs to html subdir instead of f2py HTML documentation is installed into /usr/share/doc/html/${PF}/f2py, which is somewhat misleading. Should go into /usr/share/doc/html/${PF}/html instead.
Oops, shold be /usr/share/doc/${PF}/f2py and /usr/share/doc/${PF}/html.
