Hi Alex,

I tried the example you gave to use the "cargo-update-recipe-crates" class.

I did just that, but "devtool build hippotat" failed:

I did try to add BB_NO_NETWORK = "0" to conf/local.conf but it didn't help.
Any clues?

Maybe we could use an example that's simpler to build and with fewer 
dependencies...
Cheers
