Re: OSX gnuradio/uhd issue

Oh darn, way to much multitasking, thats my mistake. I did have that
issue,
when I deleted the folder and had git recreate it I forgot to checkout
the
next branch. I recognized I did this and resolved the issue. Thats when
I
get a new error, I must have flipped between to many windows and C&P’d
the
wrong error msg

the error Im getting with the next branch, confirmed with the link you
provided

You have a partially out of date or multiple installs of gnuradio:

This is the master branch:

http://gnuradio.org/cgit/gnuradio.git/tree/gnuradio-core/src/python/gnuradio/gr/top_block.py#n129

This is the next branch:

http://gnuradio.org/cgit/gnuradio.git/tree/gnuradio-core/src/python/gnuradio/gr/top_block.py?h=next#n129

Can you post the output of
