David,

This is a new development.  MrSID support was implemented by Andrey Kiselev
in the last 2 months under a contract from i-Cubed specifically to allow
use of MrSID in MapServer.

On Linux (and presumably other Unix platforms) you would configure with the
--with-mrsid=(dir) switch.  The MrSID DSDK on Linux requires a very specific
version of gcc, so everything else (GDAL, and MapServer) will need to be
compiled with the same version.

On Windows set the MRSID_HOME variable in the GDAL nmake.opt file.

Some additional details are available in the GDAL "building from source"
page, and in MrSID format page itself.  Followups on build problems should
go to the gdal-dev list.

I would add that due to the licensing of the MrSID libraries, I am unable
to redistribute binaries of GDAL utilities or MapServer with MrSID support.
You will need to license the DSDK from Lizardtech and build GDAL yourself.

Best regards,
