I've been unable to compile the patch. 

First, the patch seemed not to apply cleanly. Patch complains about a
malformed patch at line 256 although that line looks OK to me.

I applied the patch by hand.

But then the variable cosmic_importance does not seem to be declared
anywhere. So you get errors:

influence.c: In function `accumulate_influence':
influence.c:222: `cosmic_importance' undeclared (first use in this function)

etc.

I gather cosmic_importance is a global variable.
