rosbuild manifest.xml error [SOLVED]

edit

Hello,

I have installed ros fuerte in ubuntu 12.04. Now I am compiling my stuff, but i get this error (in electric+ubuntu10.10 works perfectly):

rosbuild manifest.xml error

[rosbuild] Building package hyselam_topo [rosbuild] Error from syntax check of hyselam_topo/manifest.xml

My manifest file:

<package> <description brief="hyselam_topo"> hyselam_topo </description> <author>fbnsantos</author> <license>BSD</license> <review status="unreviewed" notes=""/> <url>http://ros.org/wiki/hyselam_topo</url> <depend package="std_msgs"/> <depend package="rospy"/> <depend package="roscpp"/> <depend package="rosbag"/> <depend package="bfl"/> <depend package="geometry_msgs"/> <depend package="sensor_msgs"/> <depend package="nav_msgs"/> <depend package="tf"/> <depend package="image_transport"/> <depend package="opencv2"/> <depend package="cv_bridge"/> <depend package="qt_build"/> <depend package="roscpp"/> <depend package="std_msgs"/> <rosdep name="libqt4-dev"/> <rosbuild2&gt; <depend="" package="qt_build"/> <depend package="roscpp"/> <depend package="std_msgs"/> <rosdep name="libqt4-dev"/> </rosbuild2&gt;>

Can someone help me on this?

Another related question:

I have tried with <rosdep name="libqt4-dev"/> and with <depend package="libqt4-dev"/> what is the diference here?
