installing rtl-sdr and whether I need to reinstall gnuradio

Hi, In reading the directions for rtl-sdr installation, I'm curious if following line in the Software section (http://sdr.osmocom.org/trac/wiki/rtl-sdr#Softwarer): "Please note: prior pulling a new version from git and compiling it, please do a "make uninstall" first to properly remove the previous version" means to uninstall my gnuradio installation, or if I have one, just the rtl-sdr software? I don't have any rtl-sdr software installed yet, but I do have a recent gnuradio installed (v3.6.?) on Ubuntu 12.10. Thanks for your help. '73' Mike, KB1QVO
