Installation failing in 2018.03

[JJ]

That would be Ubuntu, with this error:

===> Testing: Data::Dump::Tree:ver<1.8.0>:auth<github:nkh>
Cannot instantiate a native type
  in block <unit> at t/48_type_NativeCall.t line 45

Looks like the code this test is relying on changed here:

rakudo/rakudo@e0af68a

Bisect log shows the change here:

https://gist.github.com/Whateverable/9768d709bd427e644e2e1e8b9862008c

For a while, it was deprecated, and the bisect log shows the new syntax:

Deprecated since v2017.09.403, will be removed with release v2018.01!
Please use (my num64 $ = 888e0) instead.

This allows the test to pass:
