Hmmmm. that doesn't sound good at all. I am using Linux-x86: g.version -b -r GRASS 6.5.svn (2009) # ./configure --with-tcltk-includes=/usr/include/tcl8.4 --with-postgres --without-odbc --with-mysql --with-mysql-includes=/usr/include/mysql/ --with-freetype --with-freetype-includes=/usr/include/freetype2 --with-readline --with-cxx --enable-largefile --with-postgres-includes=/usr/local/pgsql/include/ --with-postgres-libs=/usr/local/pgsql/lib/ --with-sqlite --with-python --with-proj-share=/usr/local/share/proj/ --with-cairo $Revision: 37100 $ $Date: 2009-05-10 04:34:32 -0700 (Sun, 10 May 2009) $ v.delaunay -l in=archisites out=t d.vect t col=red d.vect archsites icon=basic/box size=8 attached is the output.
