Build of OpenConnect 7.05+ for EL6?

[Oliver Hernandez]

I'm on a RHEL 6.8 system and need the version of OpenConnect with Juniper
support.  I cannot find any version higher than 5.03 in any EL6 repos, and
failed at manually installing a downloaded RPM of OpenConnect 7.06 because
of 100's of missing dependencies that I suspect are part of an EL7 OS.  Is
there a build of OpenConnect 7 for EL6 systems available anywhere?  If not,
before I attempt to build from source, is version 7 compatible with EL6?
Thanks!
