-If you unpack a perl source kit with a name containing multiple periods on
-an ODS-5 volume using recent versions of vmstar (e.g. V3.4 or later) you may
-need to be especially careful in unpacking the tape archive file. Try to use
-the ODS-2 compatability qualifiers such as:
-
- vmstar /extract/verbose/ods2 perl-V^.VIII^.III.tar
+As of version 5.10.0, Perl will still build and run on ODS-2 volumes,
+including on VAX, but there are a number of modules whose temporary
+files and tests are much happier residing on ODS-5 volumes. For
+example, CPANPLUS will fail most of its tests on an ODS-2 volume because
+it includes files with multiple dots that will have been converted to
+underscores and the tests will have difficulty finding them. So your
+best bet is to unpack the Perl source kit on an ODS-5 volume using
+recent versions of vmstar (e.g. V3.4 or later). Contrary to advice
+provided with previous versions of Perl, do I<not> use the ODS-2
+compatability qualifier. Instead, use a command like the following:
+
+ vmstar /extract/verbose perl-V^.VIII^.III.tar
