This bug occurs because libmap lacks proper stubs for msSLDApplySLD,
msSLDApplySLDURL, and msSLDGenerateSLD.  Until that is fixed, you have
2 options: 1) hack your mapscript.cs and mapscript_wrap.c files to
comment out these functions or 2) build WMS server and client support
into your libmap.

I've entered a new bug into our tracker:

   http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1247

Add yourself to the cc list to follow progress.
