It appears to be caused by the clean_RPATH() function, which has this line:

      rpath=`objdump -x $Candidate | grep 'RPATH' | sed -e's/^ *RPATH *//'`

If the objdump'd file does not have any RPATH, the whole statement will fail, since set -o pipefail is in effect.  This terminates the script, since set -e is also in effect.

The line can be replaced with this instead:

      rpath=`objdump -x $Candidate | sed -ne'/RPATH/{s/^ *RPATH *//;p;}'`
