One thing you may need to do is change the ``mkdir'' to ``mkdir -p'' above.
The -p option requesting that mkdir create any missing parent directories.
However, older mkdir's don't support it, so here's a small script I
whipped up for you:

#! /bin/sh
# simulate a "mkdir -p"
parent()
{
    if test \! -d $1 ; then
        parent `dirname $1`
        mkdir `echo $1 | sed 's@/$@@'`
    fi
}
usage()
{
    echo "mkdirp: Usage: mkdirp dirname"
    exit 1
}
if test $# -ne 1 ; then
    usage
else
    parent $1
fi
exit 0
