Re: unable to install async_graphics with opam

Hi

The first error is an ocamlfind error, the second message is from Opam.

So it seems that opam has marked async as installed but something in the
installation went wrong anyway (which could explain why ocamlfind does not
find it)

you should try `opam remove async` and the retry 'opam install
async_graphics'


Cheers
Seb
