humm, despite aptitude's inability to find it, apt did install it and 17 
other packages.  That got me to yapps2 which pulled in 9 other packages, 
the intltool-extract, which apt can't find to install.

So at this point I skipped fwd to building the .deb, useing 

#>$ dpkg-buildpackage -b -uc

and its checkdeps is giving me a 6 line list of stuff to apt install. 
Just 60% of the first line is 842 MB of additional disk space will be 
used.  But its a 64GB card, shrug. Not quite 1.5GB of stuff pulled in.

First pass bailed out, couldn't load yapps although yapps2 was installed.  
Guessed around with apt and it finally installed python-yapps.  That 
satisfied it it so the deb is under contruction again.  This will take a 
while.  So if anyone is following along, they can.

Based on the description above, I'd say yes.

3.4.9 covers wheezy IIRC.  Wheezy is slowly being replaced with stretch 
or buster here as bit rot on spinning rust takes its toll. Some growing 
pains but they go away from a host based network by expunging 
avahi-daemon and dhcpcd. And runs sweet thereafter. Otherwise you'll be 
limited to your local net by routing trying to use a 169.254 address for 
inet access. Look at ip r returns if you can ping your local net but 
can't ping yahoo.com.

LinuxCNC has a problem compiling with kernel > 2.14 due to:
https://lkml.org/lkml/2017/9/30/189
There was already a pull request for a fix:
https://github.com/LinuxCNC/linuxcnc/pull/642
But last night (forgetting that experimental branches also get auto built,
and wanting to test for compatibility with previous version) I pushed:
https://github.com/LinuxCNC/linuxcnc/commit/0dbbfb3ae106feea27dab4753ae40c21b6ea06d3

I should have put this in an experimental branch first, and then it
should have been put in 2.8 (and maybe 2.7)

Questions:

Should it go in 2.7?

Does it need to be wrapped in kernel version macros? It compiles fine at
least as far back as kernel 3.4.9, so perhaps it is not worth bothering?
