I pushed the patch for cl-flow as
c03da7edb0bc4bb48c2f8e00e1ef5932c399f800.

Concerning cl-gamepad, is the library working even when all the gamepad
mappings are missing?

I took a quick look to the issue with the 'list-devices' function, and
apparently the compiler is expecting it to be in the
'org.shirakumo.fraf.gamepad' package, however it is defined in the
'org.shirakumo.fraf.gamepad.impl' package.
Maybe you could ask upstream about it?
