Gnuradio

Hi,

In my Computer I have a directory named gnuradio and another named
gnuradio.20110728200144

this was done I believe after downloading and building the script from
http://www.sbrac.org/files/build-gnuradio

does anyboady know whether I should delete one of those directories? all
commands seem to work fine in both directories, like uhd_find_devices
and usrp_probe. Also I have uhd and uhd.20110728200144

I was just wondering whether having both directories of gnuradio and uhd
might interfere when installing other programs like openbts.

Thanks in advance,
Walter
