Intermittent errors when loading modules in ActivePerl 5.8.0

    I'm getting intermittent strange error messages when I try to load any
    module in even a very simple Perl script, such as:

    ------------------------
    #!/usr/local/bin/perl -w

    use strict;
    use Digest::MD5;
    ------------------------

    The above script will run fine (yes, I know it doesn't do anything)
    sometimes and other times generate the following error:

    ------------------------
    Perl v7.1000.0 required (did you mean v7.010?)--this is only v5.8.0,
    stopped at /usr/local/lib/perl5/5.8.0/AutoLoader.pm line 3.
    BEGIN failed--compilation aborted at
    /usr/local/lib/perl5/5.8.0/AutoLoader.pm line 3.
    Compilation failed in require at
    /usr/local/lib/perl5/5.8.0/sun4-solaris-thread-multi/DynaLoader.pm
    line 22.
    Compilation failed in require at
    /usr/local/lib/perl5/5.8.0/sun4-solaris-thread-multi/Digest/MD5.pm
    line 12.
    Compilation failed in require at ./test.pl line 4.
    BEGIN failed--compilation aborted at ./test.pl line 4.
    ------------------------

    There's nothing but <I>use 5.006_001;</I> (no quotes) on line 3 of
    AutoLoader.pm, and the other modules just call each other
    (MD5->DynaLoader->AutoLoader), so I'm not sure what I'm chasing but I
    believe I am getting a useless error message at this point. This same
    Perl installation (sparc-platform, Solaris 8, Sun V880) is running
    fine on other servers. Any help would be greatly appreciated, as I'm
    no UNIX master by any stretch of the imagination.

    For what it's worth, here's the output of <I>perl -V</I>:

  2. Hi Louie,


    When you say "sometimes" and "other times", are there any other differences other than the time?

    In other words, might it be to do with who you are logged in as, working directory, library paths, environment variables and so forth? Might it also be to do with what is currently mounted via NFS?

    I suggest you dump the environment to a file when it works, and again on some occasion when it doesn't, and diff the files.

    Cheers,
    Ben Liddicott

    Unfortunately, the "sometimes" and "other times" are within seconds of
    each other, with the same environment, user, etc. I can just run the
    same script over and over again and it sporadically throws errors.
