I guess you are referring to the script `build-gnuradio`[1] recommended 
by the gnuradio wiki[2].
This script fetches the master of gr-osmosdr from the upstream osmocom 
git repo but the master of rtl-sdr form a fork by patchvonbraun[3].

gr-osmosdr depends on rtl-sdr and since commit 3c7d3f16 gr-osmosdr 
requires patches in rtl-sdr which introduced bias-tee support (for 
respective hardware).
Those patches are applied in the latest master in the upstream git repo 
of rtl-sdr, but not in the fork by patchvonbraun.
Thus the build fails.

I recommend to modify the build-gnuradio script in a way to use the 
upstream repository of rtl-sdr[4], or to pull the latest changes from 
upstream into the fork by patchvonbraun.
