Okay, it wasn't clear from the commit message that this was your true 
intention.  The commit message said you wanted to protect the package 
metadata directory from being manipulated by more than one make process.

I believe that locking ${LOCALBASE} is not necessary unless you are 
running certain targets, e.g. check-files or print-PLIST.  I think 
locking the package metadata directory is more important as that is the 
part that can really get corrupted with simultaneous updates.  Even 
though the package tools themselves don't do any locking, we can ensure 
that the pkgsrc tree itself doesn't have multiple processes updating the 
metadata directory at the same time.
