did you checked this package?
https://www.orfeo-toolbox.org//packages/OTB-6.4.0-Linux64.run
and others?
https://www.orfeo-toolbox.org//packages/

We don't need admin rights to install otb. just unzip and it works. Same
for mac and linux.
The dependency is libc and libc++ runtime. And I think any centos6 is our
reference platforms.

Issues you asked is why we introduced binary packages for OTB.
