To further debug this, I changed the buildout.cfg to use the grok 1.4.1
release

        extends = http://grok.zope.org/releaseinfo/1.4.1/versions.cfg
        
and I removed the package grokcore.chameleon from 'install_requires' of
setup.py 

Then I changed the macro access path expression from

        metal:use-macro=        
        
        "path:context/@@dashboard/template/macros/dashboard_layout">

to

        metal:use-macro=
                "context/@@dashboard/macros/dashboard_layout">
        
Now, my extended form template renders properly inside my custom layout
macros. Can someone point me to the problem?
