The VisIt build script attempts to automate the process of building the SDF
VisIt reader plugin on a variety of platforms. By default it will try three
approaches to building the plugin. First it tries the build environment
supplied by the VisIt installation. If this fails, it will attempt to build a
parallel version of the plugin using the mpi compiler in the current search
path. Finally, it will try just building the serial version of the plugin.

VisIt build script options:
  -c: Clean up files. Do not build anything.
  -r: Rebuild. Clean up files and then build.
  -d: Build with debugging flags enabled.
  -p: Do a "public" build. This passes the "-public" flag on to the VisIt build
      system which copies the binaries into a publically accessible location.
  -n: Don't build the VisIt reader plugin.
  -u: Do build the additional SDF utilities.
  -i VISITPLUGINDIR:
      Install the reader plugin in the path VISITPLUGINDIR
  -v: Build verbosely.
  -f: Force build. This prevents the build script from checking
      g++ compatibility
  -1: Perform only the default VisIt build.
  -2: Perform only a parallel VisIt build.
  -3: Perform only a serial VisIt build.

It looks as if the visit command in your PATH has been built from source and
not installed. 3rd party plugins are not supported for this configuration.
You need to install visit properly by cd'ing to the visitX.X.X/src directory
and typing either "make install" or "make package". The latter command will
create a zipped archive which you can then unpack to the desired location.
