Using source builds on my slave (bolen-ubuntu):

Linux buildbot-ubuntu 4.1.0-x86_64-linode59 #1 SMP Mon Jun 22 10:39:23 EDT 2015 x86_64 x86_64 x86_64 GNU/Linux
NOTE: This is a 32-bit userspace system, just with a 64-bit kernel

Python 3.6.0a0 (default:e56893df8e76, Aug  7 2015, 16:36:30) 
[GCC 4.8.4] on linux

[1/3] test_tk
[2/3] test_ttk_guionly
[3/3] test_idle
All 3 tests OK.

Python 3.5.0b4+ (3.5:b9a0165a3de8, Aug  7 2015, 16:21:51) 
[GCC 4.8.4] on linux

[1/3] test_tk
[2/3] test_ttk_guionly
[3/3] test_idle
All 3 tests OK.

Python 3.4.3+ (3.4:f5069e6e4229, Aug  7 2015, 16:38:53) 
[GCC 4.8.4] on linux

[1/3] test_tk
[2/3] test_ttk_guionly
[3/3] test_idle
All 3 tests OK.

I have also adjusted the slave to run under Xvfb so the tests should
be included going forward.
