I want 2.7.
I followed these directions :
Getting Started V2.7.0-pre6-55-g4393531, 2015-05-25
3.7.1 Installing on Debian Wheezy (with Preempt-RT kernel)
Well, the actual binaries are at www.linuxcnc.org/dists/wheezy/2.7-uspace/
(ie, you seem to have dists/wheezy back to front. But I am not sure how you configured things so it might not be your fault.
