My PILS language with juce bindings is now available on http://www.pils.org
For the time being, I only published the MS Windows version, but it runs on Linux too, with a few quirks.
If anybody has struggled with interfacing juce to a scripting language, the juce interface generator might be of interest. It parses the amalgamated header file and chunks out the (non-trivial) wrappers needed for PILS to use juce.
In a typical installation, the interface generator is here:
C:\Program Files\PILS 2006\lib\pils\english\pils\juce\plumming-generator.pils
It is not particularly well-written and not documented - but it works and it is possible that it could be modified to generate interfaces for other dynamic languages.
