This defines two different metatargets named 'unittest_myproject' -- one is 'run'
and another 'compile'. Since there's nothing to make one of them preferred to
another in some cases, you get ambiguity...

.. as reported here.

This actually won't read ARGV, because ARGV is defined in the global
module, and each Jamfile is a separate module. I suggest you use

        import option ;
        local run = [ option.get run : : true ] ;

instead

This should work. What is the exact and complete error you get?
