Wrong MpPortableUtil subclass selected on Pharo 11 about msgpack-smalltalk

[tatut]

Can confirm. The examples in README work when installing from develop branch to a fresh P11 image.

Thanks for the feedback.
Normally if you install MesssagePack via Metacello, the correct DialectSpecificClass (MpPhPortableUtil) should be set. BaselineOfMessagePack >> preLoadForPharo does the trick.

BaselineOfMessagePack >> preLoadForPharo
	Smalltalk globals at: #MpPhPortableUtil ifPresent: [ :cls | cls initialize].

But in Pharo 11, the method seems not to be called automatically. I'll investigate the issue.

Now the error was fixed in develop branch: https://github.com/msgpack/msgpack-smalltalk/tree/develop
Please confirm it. I'll close the issue after a while.
