thanks for posting this.  This is a problem caused by grsec tightening
security on systems.  While this is not very standard across linux
systems, Pentoo in particular does this by default (although a
non-hardened option is available).  In pentoo, it is possible to disable
most of the grsec protections with the handy script "toggle_hardened".
Using this script to temporarily disable hardening for certain tasks,
and then reenable it after you are done is an additional option for
users to consider.  Both should work, however, each has benefits and
drawbacks.

this shouldn't be needed at all, all gnuradio type stuff is python 2.7
at this time.
>> paxctl -m `which python2.7`
This works, however the following command is more preferred:
paxctl-ng -m `which python2.7`

Thanks,
