syniperl has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to install IPC:Shareable in a 64 bit linux system and received the following errors
1) t/10av.t ...... 1/11 Can't use string ("3") as an ARRAY ref while "strict refs" in use at /home/ec2-user/.cpan/build/IPC-Shareable-0.60-WmQJPw/blib/lib/IPC/Shareable.pm line 455.
2) t/10av.t ...... Dubious, test returned 255 (wstat 65280, 0xff00)

I tried installing through
a) MCPAN
b)Force install using the the code.
c) using perl 5.10 and 5.12 (both built for 64bit).
d) yum install
'yum search IPC' gives only

    into 

        $#{$self->{_data}} = $n - 1;

    fixes the issue for me.

    (modify blib/lib/IPC/Sharable.pm in the build directory before running the tests with make test)

      This problem was reported two years ago. It looks like this module isn't being maintained.

      Some background for those interested:

      There was a bug in Perl such that 

      $#{ @array }

      [download]

      was interpreted as 

      $#{ \@array }

      [download]
      instead of 
      $#{ scalar(@array) }

      [download]

      IPC::Shareable's test relies on this bug, but it was fixed in Perl 5.10. Note the lack of 5.10.x and 5.12.x passing results.

        Looks like module hasn't been updated since 2001
