That's so dope, but it's incomplete. You forgot to split out lines with multiple records. I tried to extend your idioms up front but ended up post processing:

perl -MList::Util=uniq -le "$,=$/; @_= uniq( qx(perldoc -uT perllocal)
+ =~ m(<EXE_FILES: (?:.*/)?(.*)>)g); for (@_) { @x = split/\s+/; push 
+@z, @x} print sort @z"
