mummerplot defined(%hash) issue

[sheraghty]

Using the mummer-4.0.0rc1 release of mummer and running into some issues with using mummerplot. When attempting to run the mummerplot, I get the following error:

Can't use 'defined(%hash)' (Maybe you should just omit the defined()?) at /usr/bin/mummerplot line 884.

However, there is not a defined(%hash) at this line. I've looked at some older threads where people have had this issue and it seems that they were able to resolve it by removing defined at line 884 and some other spots throughout the code - see link for details. Upon inspection of the version of mummerplot that comes with mummer v4.0.0rc1 the defined at line 884 (and the other places mentioned in the linked issue thread) have already been removed. Is there any other edits that need to be made to the code to make it usable?

Using perl v5.32.1
