Because libopenvrml uses these variables to initialize some global
objects.  If it can't find what it needs, that initialization fails;
that is, an exception gets thrown.

On Windows, throwing an exception during static initialization appears
to be a bit dodgy; the resulting crash gives a message that isn't
ideally lucid.  The message could probably be improved (with some
platform specific code); but the result (a crash) will be the same.

I'm not 100% clear on what this means to you.  The provided project
files build libopenvrml as a DLL.  And the node implementations and
scripting engines all live in plug-in DLLs.  OPENVRML_NODE_PATH and
OPENVRML_SCRIPT_PATH are used to find these bits.  OPENVRML_DATADIR is
used to find the component XML descriptor files.

What did you set them to?
