That seems to have loaded ok but references a class XMLString that I have had no success in finding and is of course Undeclared. Anyone know where it can be found?

That's why Xtreams should be loaded via Metacello, so that all 
dependencies are loaded along with it.
Metacello will load monty's version of XML-Parser, which contains the 
XMLString class (which is still not backwards compatible, so if you 
need XML for anything else, then you'll have to write a new actor to 
generate html, but the parser will still be fine as-is).
Here's how to do that:

1. Install Metacello from the Docking Bar's Tools menu's Metacello entry
2. Evaluate (Smalltalk at: #ConfigurationOfXtreams) project bleedingEdge load


P.S.: The actual problem is that people had started to make projects Pharo 
compatible on squeaksource, often by breaking Squeak compatibility (e.g. 
SmaCC, and partially Xtreams), and later moved on to smalltalkhub/github, 
leaving the broken (from both Squeak's and Pharo's POV) code rot on

>>> SmaCC doesn’t load into Squeak anymore. As Levente’s post a few back said, the parser to have is in Xtreams. It has a PEG parser with a wiki grammar. You need to  write an Actor subclass for it. [1] The VW package comes with Actor subclass examples (i.e. PEG.WikiGenerator).
