I think I found a dependency problem with libsdl if this clues you into 
anything.  

I originally installed gnuradio with synaptic and everything worked, but I 
can't even get that installed again, it complains about trying to overwrite 
usr/lib/libusrp.la which is also in package libusrp0-dev

thanks for your help on this.  I would really like to just get back to the 
synaptic install and capture a long file with usrp_rx_cfile.py

 sudo apt-get install libsdl1.2-dev

You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
  libgnuradio-usrp: Depends: libusrp (= 3.2.2-1) but it is not going to be 
installed
  libsdl1.2-dev: Depends: libx11-dev but it is not going to be installed
                 Depends: libglu1-mesa-dev but it is not going to be installed
                 Recommends: libxt-dev but it is not going to be installed
                 Recommends: libxext-dev but it is not going to be installed
                 Recommends: libaa1-dev but it is not going to be installed
                 Recommends: libesd0-dev but it is not going to be installed
                 Recommends: libdirectfb-dev (>= 0.9.22) but it is not going to 
be installed
                 Recommends: libcaca-dev but it is not going to be installed
  python-gnuradio-usrp: Depends: libusrp but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a 
solution).
