Zhonghai,

Note it doesn't matter if MapServer is built with libcurl, what matters is
whether GDAL is built with libcurl.  I'd suggest you set the CPL_DEBUG
environment variable to see if there is any more info available from GDAL.

Also verify that the HTTP driver is available in GDAL
(eg. gdalinfo --format http)
