Hi,  
I am trying to run an old application that was working previously but  
when I upgraded to 3.6.1 I get the error in the title. Has anybody  
encountered and solved this problem?

The swig file was moved, you need an extra line to add to your swig  
include path, in your case the missing file can be found in

/usr/local/include/gruel/swig
