Have you tried closing the shapefile after it's been created and then
repoening it in read access?

I ran into a similar problem (on Windows)... I was creating shapefiles
using the PHP/MapScript which is based on the same functions as the Perl
MapScript, and I realized that the last changes to the shape file do not
appear to be flushed to disk until the file is closed.  Closing the file
and repoening it solved the problem... I have to admit that I didn't
look into the MapServer code to try to understand what was really
happening.
