On my system, there are three copies of run-mozilla.sh: In /opt/firefox, /usr/lib/mozilla, and /usr/lib/nvu. The variable MOZILLA_FIVE_HOME=/usr/lib/mozilla. As a result, the script /usr/bin/nvu gives an error that it could not find /usr/lib/mozilla/nvu-bin. I changed the last few lines of /usr/bin/nvu to: if [ $debugging = 1 ] then echo $dist_bin/run-mozilla.sh $script_args /usr/lib/nvu/$MOZILLA_BIN "$@" fi exec "$dist_bin/run-mozilla.sh" $script_args "/usr/lib/nvu/$MOZILLA_BIN" "$@" and it works now.

As I have just included rpath and 1.0-r2 works for everyone else closing as worksforme. If you have any issues with -r4 open a bug and I will address it.
