Hello Christian

# # # #
SHORT VERSION... now fixed - thanks.

# # # #
LONG VERSION...
My as-was details ...

bryan at ASUS-K75DE:~$ apt-cache policy libxrandr-dev
libxrandr-dev:
  Installed: (none)
  Candidate: 2:1.4.2-1
  Version table:
     2:1.4.2-1 0
        500 http://nz.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages

 ... clearly missing the trusty-updates bit
===
(using Synaptic Package Manager)
Software & Updates - only checked box was 'Important security updates
(trusty-security)'
i.e. 'Recommended updates (trusty updates)' NOT selected

So I selected 'Recommended updates' & updated 150+MB
===
My new details ...

bryan at ASUS-K75DE:~$ apt-cache policy libxrandr-dev
libxrandr-dev:
  Installed: (none)
  Candidate: 2:1.5.0-1~trusty1
  Version table:
     2:1.5.0-1~trusty1 0
        500 http://nz.archive.ubuntu.com/ubuntu/ trusty-updates/main amd64
Packages
     2:1.4.2-1 0
        500 http://nz.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages

===
and libxrandr-dev now installs :-)
