I can confirm that Horde_Mime 2.7.0 works just fine.  See, e.g.,  
https://travis-ci.org/horde/horde/builds/53897531 (the tests would  
fail if the various components of the Horde_Mime package could not  
load Horde_Mime_Headers_Extension_Mime)

Sounds like you possibly have an issue with your PHP caching script  
filenames or something similar.  Try restarting PHP or power cycling  
your system.
