### Since not all tests were successful, you may want to run some of
### them individually and examine any diagnostic messages they produce.
### See the INSTALL document's section on "make test".
### You have a good chance to get more information by running
### ./perl harness
### in the 't' directory since most (>=80%) of the tests succeede
