You may need to set up a foreign symbol for the unpacking utility of choice.
-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
or:
- vmstar -xvof perl-5^.8^.3.tar
+ vmstar -xvf perl-5^.10^.0.tar
-If you neglected to use the /ODS2 qualifier or the -o switch then you
-could rename the source directory:
+Then rename the top-level source directory like so:
- set security/protection=(o:rwed) perl-5^.8^.3.dir
- rename perl-5^.8^.3.dir perl-5_8_3.dir
+ set security/protection=(o:rwed) perl-5^.10^.0.dir
+ rename perl-5^.10^.0.dir perl-5_10_0.dir
-Perl on VMS as of 5.8.3 does not completely handle extended file
-parse styles such as are encountered on ODS-5. While it can be built,
-installed, and run on ODS-5 filesystems; it may encounter
-trouble with characters that are otherwise illegal on ODS-2
-volumes (notably the ^. escaped period sequence).
+The reason for this last step is that while filenames with multiple dots
+are generally supported by Perl on VMS, I<directory> names with multiple
+dots are a special case with special problems because the dot is the
+traditional directory delimiter on VMS. Rudimentary support for
+multi-dot directory names is available, but some of the oldest and most
+essential parts of Perl (such as searching for and loading library
+modules) do not yet fully support the ODS-5 caret-escape syntax.

hangs (some tests can take upwards of two or three minutes, or more if
you're on an especially slow machine, depending on your machine speed, so
