Check if the PATH has the same values both with and without sudo. Apparently it cannot find bundle just because it is not listed in PATH

You can compare the outputs of following two lines

$ echo 'echo $PATH' | sh
$ echo 'echo $PATH' | sudo sh

Ideally sudo is supposed to leave PATH untouched. But this might be a side issue of your hosting distribution.

Edit by original poster. Output is:

[root@desktop etc]# echo 'echo $PATH' | sh
/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
[root@desktop etc]# echo 'echo $PATH' | sudo sh
/sbin:/bin:/usr/sbin:/usr/bin:/user/local/bin
[root@desktop etc]#
