This does not break compatibility with bash-3.x.   Just bash-4.0 which 
had a bug in it in the way it handles the type tests.

In bash-4.0 _only_:
if [[ $(type -t build) == "function" ]]
sets of the error trap if the build function does not exist.  In all 
other version of bash, that works fine.

I am fine with dropping compatibility with bash-4.0 because any 
distribution (am I am including MacOSX and cygwin under that banner) 
that upgrades to bash-4 now will not be using bash-4.0.
