Reported by @pmattern:

After upgrading Python Sphinx to 1.5 setting -DREBUILD_MANUAL=on triggers FTBFS, see make output below. Problem ceases after reverting to Sphinx 1.4.9. Both times quark-sphinx-theme 0.4.1 built against the respective Sphinx version before starting the attempts to build SpeedCrunch.

    @pmattern How did you upgrade to Sphinx 1.5? According to the error message, requests isn't it installed which Sphinx 1.5 now depends on. I just tried it on Ubuntu 16.04 with Sphinx 1.5 installed via pip and things built (mostly) fine.

    There's another problem with 1.5 however: the qthelp builder now seems to override the theme from conf.py with an unstyled theme. In the words of the changelog, "QtHelpBuilder uses nonav theme instead of default one to improve readability." However, that overrules our custom theme. I'll look into it some more.

    To wrap up my hijack, I fixed the theme.

    Anyway, this seems to be a bad Sphinx installation rather than a SpeedCrunch bug.

    The problem is caused by the lack of Requests and has nothing to do with SpeedCrunch.
    On Arch Linux SpeedCrunch compiles flawlessly after installing package python-requests or when Sphinx is installed from the PyPI in the first place which pulls Requests by default.

    On a side note the role of Requests as of Sphinx 1.5 doesn't look exactly obvious to me.
    Being pulled by pip install sphinx suggests it's a rather crucial one. But when Sphinx is built like it's done by the Arch Linux package python-sphinx, see command build() in PKGBUILD, there's no warning that Requests is missing let alone FTBFS. Also, the only upstream documentation I could find isn't exactly verbose.
    Meanwhile there's an Arch Linux bug report addressing the problem as well.
