[GRASS5] GMSL/g3d error on OSX compile

[Kirk R. Wythers]

I'm building GRASS53 on Mac OSX. Here is my configure script:
./configure \
--with-postgres-includes=/sw/include/postgresql \
--with-postgres-libs=/sw/lib/postgresql \
--with-gdal=/usr/local/bin/gdal-config \
--with-includes=/sw/include \
--with-libs=/sw/lib \
--with-opengl-includes=/usr/X11R6/include \
--with-readline \
--with-proj

I'm getting an error:
Compilation error in module: src.contrib/GMSL/g3d (ignored)

Running gmake5 on /src.contrib/GMSL/g3d/src3d/raster/ gives:

Can this be fixed by trying to compile with GLX or MOTIF? Or is this  
just not a big deal?

Thanks,

Kirk
