Tried to build on Ubuntu Mate and got this:

Please be more specific: what Linux version is it, and which version of
Vc are you including? The error is in Vc, did you build Vc from source?
That's most likely to succeed, please pick the 1.4 branch. You can find
instructions for compiling Vc from source on my bitbucket site, please
refer to the section 'Building pv on a debian-based system'.
If you are in a hurry to get code running and want to work around the Vc
problem, you can compile without Vc: just remove the '-D USE_VC'
statement in the makefile (compiler_flags, line 43). The resulting
binary will be about 30% slower than the Vc version. For experiments
trying to get the code compiled, you may also want to check out the
'native' branch of pv, which offers two non-Vc targets and has faster
turn-around.
Good luck
Kay
