Hey all -
I've seen some traffic both on and off-list discussion getting GNU Radio running in CentOS. The most recent one was CentOS 7.0, I believe, but there's also been some discussion of CentOS 6.8.
In addition to the backported changes, you'll also need to install boost-1.48 from the EPEL repositories.
Hopefully this is useful to someone. I haven't spent a ton of time testing it, but at a quick glance things seem to be in order. If you use this and find any issues, please let me know.
Cheers,
Ben
