I'd rather not.  Are you 100% certain that the python2 script is only 
ever used when building with the dtrace option?

Just for context I've had to fix this a number of times in the past when 
others have tried to remove the python27 dependency, which has wasted my 
time and caused build breakages for users, so I'm particularly sensitive 
regarding this issue.

It's not a runtime dependency, and so the risk of breaking the build far 
outweighs the small advantage for people who build from source in my 
opinion.  I'd honestly rather see effort put into just fixing the script 
in question and submitting a python3 compatible version upstream if it's 
something people care about - that way everyone wins.
