[Discuss-gnuradio] Error Make gnuradio

Hello, I using ubuntu 11.04 and I want to install the gnuradio, but
when I do "make" for gnuradio 3.3.0 or 3.3.2 i unfortunately get this:

gnuradio make[5]: * [libgnuradio-qtgui.la] Error 1

......and i've done this and i get the same error:
-sudo apt-get build-dep gnuradio
-install all the dependencies on the gnuradio build guide page ( i got installed other stuff)
-then the usual steps of building from source

please help me!

Thanks!!
