Than there is the question for me...... why IS there a variable $rcStep$???? this is exactly as useless as in every OTS Theme has to include the personal.rc file itself.
I always include my personal.rc in the mainroot step.rc bevore
include "$dirTheme$$rcStep$"
I had never any problems and I do not need this useless line in my theme step.rc anymore. In every Theme it is the same, so why in the theme step and not in the mainroot step....

back to the $rcStep$ variable, I think that there is also a useless line called: rcStep = "step.rc".

*just think about that ;)*
