    Apparently you've imported a module which exports a function called 'mkdir' elsewhere, or in some other way made it ambiguous. You can get rid of the error by following either suggestion. How about: 
    CORE::mkdir $dir, 0755
or BL::GenLib::MiscErr("Could not make $dir");

    Also, you probably want the lower precedence or instead of || as indicated.

      works like a charm. Thanks for your help.

    There's a precedence problem with this code, too which might cause problems.
    You either need to use 'or' rather than '||' or to wrap the arguments to mkdir in parentheses. What you're saying here is effectively: 
    mkdir $dir;
0755 || BL::GenLib::MiscErr("Could not make $dir");

    So you'll never get the error.

    I found Tom Christiansen's style guide pretty useful for correcting my precedence problems.
