Error with DFBrowser in OpenCASCADE6.3 and mandriva linux 2010.0

Hi, I have compiled with no errors opencscade6.3 on mandriva linux 2010.0.
I have installed opencascade in /opt/OpenCASCADE.

I assign values to all variables referenced into the env.sh file, using export command, and DRAWEXE works.
I run ./DRAWEXE , and I write pload ALL.In this moment I get this error

Draw[1]>pload ALL
Cannot load Debug Browser library.DFBrowser command is not attached

I take a look around here http://www.opencascade.org/org/forum/thread_10901/
and in this moment I realized that I haven´t any /tool folder in /opt/OpenCASCADE, like comment Aurélien RIOU in the linked post.

I've compiled opencascade with this options

autoreconf -fi
flags="--with-tcl=/usr/lib/tcl8.6 \
--with-tk=/usr/lib/tk8.6 --disable-debug --enable-production \
--enable-wrappers=yes --enable-wok=yes \
--enable-draw=yes --with-java-include=/usr/lib/jvm/java-1.6.0-sun-1.6.0.16/include"
./configure $flags --prefix=${RPM_BUILD_ROOT}

Would I need some external module like this?

At the moment I can see only a very little window called DRAW with a few options,File, views,displays,curves,surfaces

You can see this image to have an idea
