Looking at your book to be (very promising) Alas there is check_sum problem. Is there a different way/ repository to use?

Due to some errors while processing { lwt.2.4.3, camomile.0.8.3 }, the following actions will NOT be proceeded:

• install utop.1.3.0
• install lambda-term.1.2
• install zed.1.2

==== ERROR [while installing camomile.0.8.3] ==== Internal error: Wrong checksum for http://opam.ocamlpro.com/archives/camomile.0.8.3+opam.tar.gz

==== ERROR [while installing lwt.2.4.3] ==== Internal error: Wrong checksum for http://opam.ocamlpro.com/archives/lwt.2.4.3+opam.tar.gz 'opam install utop core_extended' failed.

Context:

Note that the above commands will take some time to run. When they're done, you should have a file called ~/.ocamlinit in your home directory, to which you should add at least the following.

Hmm. This sounds like an installation problem. Assigning to Anil.

Probably some temporary opam problem, probably from some mistake we made a long time ago. Just blow away your .opam and reinstall.
