I've successfully installed the latest git on top of lucid.
all seems OK, except on make check I get

gr_fft_filter_ccc.cc: In member function ‘void
gr_fft_filter_ccc.cc:133: error: ‘stderr’ was not declared in this scope
gr_fft_filter_ccc.cc:134: error: ‘fprintf’ was not declared in this scope

I found fprintf in the indicated cc file, but haven't got the faintest
idea how to fix. chased in the wiki, and found sa change for fprintf but
not how to fix (complete newbie to all things Linux)

I did the install anyway, and I found the USRP OK,

crw-rw---- 1 root usrp 189, 1 2010-05-31 13:48 002
I have an FX2400 and a basicX installed in the USRP, but that's not of
course apparent from above.

ImportError: libusrp.so.0: cannot open shared object file: No such file or

So, off to synaptic, and I find NO libusrp, instead there's something
called libusrp0 installed. I'm guessing this is the problem, but don't
know. This I know doesn't have anything to do with the filter problem. I
took my last swig some 30 years ago, so that's not the problem.

so, as a neqwbie, I'm stammagasted and stumped.
Is there help?
