What do you get when you run:

otool -L /System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices 

On my 10.10 and 10.11 systems, the first two lines are:

/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices:
	/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices (compatibility version 1.0.0, current version 48.0.0)

So, the OS provides ApplicationServices version 48.0.0 which is backward-compatible with 1.0.0. I'm not sure where you would have encountered a version 64.0.0 of ApplicationServices; it doesn't appear Apple has released any version that high yet.

Also, what do you get when you run:

otool -L /opt/local/bin/mythavtest

Maybe you have DYLD_LIBRARY_PATH set to a value that is causing the wrong libraries to be used.
