The errortrace library is good but for development time not for this 
case.  Also it does not tell error location for each function anyway. 
Probably because continuation created not for each function.

But I found another interesting thing. The error message in DrRake and 
command line rake are different (I did not know that). And rake's 
messages more informative. That is good news for me.
