There are issues with various versions of DEC C, so if you're not running a
relatively modern version, check the "DEC C issues" section later on in this

+=head1 Unpacking the Perl source code
+
+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
+
+or:
+
+ vmstar -xvof perl-5^.8^.3.tar
+
+If you neglected to use the /ODS2 qualifier or the -o switch then you
+could rename the source directory:
+
+ set security/protection=(o:rwed) perl-5^.8^.3.dir
+ rename perl-5^.8^.3.dir perl-5_8_3.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).
+
=head1 Configuring the Perl build

a VAX or on Alpha versions of VMS prior to 7.2). But MakeMaker will not
warn you if you start out building a module too deep in a directory.
+As noted above ODS-5 escape sequences such as ^. can break the perl
+build. Solutions include renaming files and directories as needed or
+being careful to use the -o switch or /ODS2 qualifier with latter
+versions of the vmstar utility when unpacking perl or CPAN modules
+on ODS-5 volumes.

Be sure that the process that you use to build perl has a PGFLQ greater
than 100000. Be sure to have a correct local time zone to UTC offset
defined (in seconds) in the logical name SYS$TIMEZONE_DIFFERENTIAL before
