I use trap that has a function

trap '_errortrap "Caught error processing\n";exit 1' ERR INT

_errortrap() {
     local i=$1
     printf "${i}: Build failure...\n"
     touch ${FAILURE}
     exit 1
}

I then do something like this those parts that are in loops etc.

Some_statement || _errortrap

I also place a file called FAILURE into the parent fiesystem and test 
for it when I start a new package for build.

for i in list of ${stuff_to_build}; do
     [ -e ${FAILURE} ] && 'errortrap
     build_package
     do_stuff
     etc
done
