Build Pex without dbus

[bhunut-adobe]

The build instruction stated that

You don't need the python-dbus package to build user-sync, but you will need it to run user-sync if you use the dbus secure store for your credentials.

However, when I attempted to build UST, I got an error for dbus which it normal for Centos 6. It seems like dbus is still required to build.

pex: Failed to install package at /tmp/tmp6o6pfowi/dbus-python-1.2.4: Failed

OS: Centos 6.7
Python: 3.6.3
Using virtualEnv.

I've been unable to build it in 6.7 If you build it in 7, you should be able to run the pex in 6.7.

@adorton-adobe Yeah in rhel/centos 6 it usually errors out because of dbus. But the documentation now said dbus is optional from the build process.

I'm investigating. I haven't done much in centos6. But I will take a look over the next few days.

[adobeDan]

Haven't had any time to look at this. Still trying.

OK, so dbus-python is required for builds; that was an error in the README. Further, the latest version of dbus available on CentOS 6 is 1.2 but user-sync requires 1.6 or later to build. So you cannot build user-sync on CentOS 6, but you can run the CentOS 7 build on CentOS 6 (as long as you are using the same version of python 3). But I doubt it will work if you try to use the keyring.

Marking this bug as a doc bug, because there's no way to build on CentOS6. Going to fix the README.
