That's why I wanted you to try it -I was never clear on whether the 'usual' SConstruct or Jamfile would have an install 'rule' as Makefiles do. If this is not the case I'll change the code. I've been working on that section of code to improve handling of install.sh scripts and other stuff wioth no regular Makefile. The thing is that I've included the the SConstruct and Jamfile in the search for some sort of Makefile, which are then checked for an install rule. This is not really necessary any longer as we can just run the command and check for success afterwards.
Commenting out this line (710) in configure_source should fix it:
I appreciate the feedback, as usual.
