Message 189880 - Python tracker
Terry, I just tested your 2.7 patch, and it does work, but the workaround that (I think) we have both been using on 3.x to find the Tcl/Tk .dlls (copying them into PCbuild) doesn't work on 2.7 for some reason. However, if you add ..\tcltk\bin to PATH, which the PCbuild\rt.bat script (called by Tools\buildbot\test(-amd64).bat) does, your patch allows all of the test modules to run properly. I wonder if this has anything to do with issue17883's buildbot problems?
