Well, That DID solve the problem (I hadn't installed sdcc, so I did and it worked).
but now I'm trying to connect the USRP to the VMWare via usb but when I
run a sample demo I'm getting this error:

$ python usrp_wfm_rec.py

Traceback (most recent call last):
  File "usrp_wfm_rec.py", line 25, in ?
    from gnuradio import usrp
  File "/usr/local/lib/python2.4/site-packages/gnuradio/usrp.py", line 24, in ?
    from usrpm import usrp_prims
  File "/usr/local/lib/python2.4/site-packages/usrpm/usrp_prims.py", line 6, in ?
    import _usrp_prims
ImportError: libusrp.so.0: cannot open shared object file: No such file or directory

I did add a new RULE by creating the file /etc/udev/rules.d/90-usb.rules and putting this in it:

SYSFS{idVendor}=="fffe", SYSFS{idProduct}=="0002", MODE="0666"

so non-root users could access the USRP via USB.

Also when I do tail -f /var/log/messages I do get the usb:

address@hidden sadraei]# tail -f /var/log/messages
Mar 25 02:14:40 localhost kernel: usb 1-1: USB disconnect, address 4
Mar 25 02:18:27 localhost kernel: usb 1-1: new full speed USB device using uhci_hcd and address 5

Is this a recognized error?
I couldn't find any good sources on setting the usrp with the the gnu radio online
so I'm wondering if there is more to it than what I have done?

Thank you again for being so patient with my questions.
