Here is a script given to me to fix the paths problem in libraries.  It
may work for binaries, but I hvae not tested it on either, because I
understand it.

toshy:root:/home/torsten# cat `which fixlib`

if [ -z "$*" ]; then
  echo "$0 badlib goodlib"

#cd /vapp/lib
cd /usr/local/src/test/lib

grep $1 --binary-files=without-match * | while read l
  lib=`echo $l | cut -f1 -d':'`  
  cd /usr/local/src/test/lib/test
  liblocation=`find . -name $lib 2> /dev/null`  echo "Fixing
  perl -pi -e's#'$1'#'$2'#' $liblocation
