It's pretty easy, really.  Just find the libraries line, and add -lefence 
before all the other -l's

That's all you have to do.

Oh, and it will force a dump, so run ethereal in gdb, and it will dump 
whenever a malloced overwrite occurs.

Personally, I've written several malloc checkers, but I've never seen one
as gracefully simple as electric fence.  It just uses the MMU to mark
the data before and after the malloced chunk as inaccessible.  That way,
any over or under writes cause your program to dump.

Good luck,
