 The installation root defaults to /usr/local and can be modified
 by passing in the --prefix argument to "./waf configure".
 
+If you get errors on the install step to the effect of os.symlink 
+failing to make a link because the file already exists -- see GitHub 
+issue #220 and please add a comment indicating your Linux distribution
+and that you are having this problem.

+Note that the instances of #220 I have seen are failing at the
+very tail end of the install process, and are trying to install
+files that are already there... which means that you can probably
+ignore this error.  Try activating the virtualenv and running
+mfp.  If it launches, you are good to go.

  #217 | MFP must be stopped with `kill -9` in (hopefully rare) error conditions. Workaround: ^Z to stop the process from the shell, then `kill -9 %1` 
  #204 | Logging is broken when loaded as LV2 plugin 98 | Selecting connections with click or box doesn't work well.  Workaround: Zoom in and click right on the line. 
  #212 | Rendering of smooth curves on XY plot shows gaps  
+ #220 | 'waf install' can give error messages. Workaround: See the bottom of README.build; possibly no action is required. 
 
 See the tickets in GitHub for detail on what I know about these problems, and for 
 other potential workarounds.
