You left out a lot, like what operating system you are using. But
I'll guess that gr_vmcircbuf_createfilemapping is trying to mmap a
file in tmp to get shared memory, and it needs to be writable.
Perhaps using mfs or tmpfs, or some other kind of memory filesystem
for /tmp is in order.
It may be that the diagnostics are not quite right. Try
ktrace/truss/etc.
