Do you mean IO as a whole?

This code:

    use IO::handle;
    use FileHandle;
[download]

is embedded in the functions of logfile.pm, which is a custom library that I have no control over. I am trying to reference all the custom libraries in my code:

BEGIN {
    @PERL_SHARE = (
                    "/foo/custom/perl/lib/Custom_mods",
                  );
    unshift(@INC, @PERL_SHARE);
};
[download]

logfile.pm is in the Custom_mods directory.
