Hi Yunuen,
Glad to hear you were successful in completing your installation.
I don't have any experience of the error you mention, however I'd always recommend that you try searching moodle.org (using the search box at the top right of every page on moodle.org) for part of the error message e.g. "Unable to load dynamic library" as you'll most likely come across other posts, or a tracker issue, or some documentation about it, together with suggested solutions (hopefully!)
