I'm using Linux... and whatever 'gr-vmcircbuf_createfilemapping' is, is 
buried deep in the gnuradio
sources.

In this case it looks like there's a presumption about the 'user' and 
having a directory associated with
that user, where 'preferences', etc. can be read/written, rather than 
using say, /tmp or similar 'well known'
writeable location.

I'll have to do a find on the gnuradio sources to find the specific 
reference, and then figure out
'what to do'...
