You don't need xerces.  This is OK

Not required for GNU Radio, but nice to have.

Depends on your setup.  I don't install with sudo (being generally
paranoid), and have arranged things so that I'm in a group that has
write access to everything under /usr/local.  Judicious use of 
chmod g+s on directories under there is useful.

I think this was a permissions problem.  Unless you're setup to write
/usr/local and below, you will want to "sudo make install".

If you're building from CVS, you need to install the .rbf file manually.
Grab http://comsec.com/usrp/usrp_fpga_rev2_2005_10_20.rbf and install
it as /usr/local/share/usrp/rev2/usrp_fpga.rbf

We don't use the hotplug stuff.  Our library loads the firmware and fpga
bitstream when you first open the device.

There's lots of variation on usb device permissions depending on your
distribution.  Under SuSE 9.3 it "just works".  Not sure why!
Under Mandrake 10.1 I made myself a member of group usb, which is the
group that owns everything under /proc/bus/usb/*
FWIW, the gid and perms used by usbfs can be set with a mount command
option.  E.g., 

  address@hidden ~]$ grep usbfs /etc/rc.d/init.d/usb
        action "Mount USB filesystem" mount -t usbfs -o devmode=0664,devgid=43 
none /proc/bus/usb

Did you make install?  Did it work?
You might try "sudo ldconfig"
Is your PYTHONPATH set?  Should be something like:

  /usr/local/lib/python2.3/site-packages

OK!
