Gurus:  
I am trying to build gnuradio on Mac OS 10.9.5 using homebrew and I cant  
seem to get past this error:

Anybody have any ideas on how to solve this problem?

Hi Ed - The actual link command was not included in the output you  
provided, so its difficult to say exactly where the issue lies. But,  
the basic cause is that libSDL.dylib is not being included in the link  
command, and/or it does not contain the various SDL\_\* symbols that are  
not being found, and/or the .PC file for SDL (sdl.pc) does not provide  
correct linkage, and/or libSDL was built for the wrong architecture (32  
bit, not 64 bit). To the best of my knowledge, the GNU Radio CMake  
script for the gr-video-sdl component works correctly when libSDL is not  
found (meaning: it disables the component). If you want to work more on  
this, email me off list and we can summarize on list as appropriate. -
