Not sure if you still need this.  But he newest version of ruby-prof, 
0.5.0, keeps track of where code is called from.  The easiest way to see 
this is create an graph html report and look at the last column, which 
is called line.  It is a hyperlink, and if you click on it, it will jump 
you to the correct file.  Unfortunately browsers won't jump to the right 
line in a text file, but look at the end of the url and you can see what 
the line numbers is.

Hope this helps,

Charlie
