Using

./configure --disable-python --disable-dyndrivers --disable-shared

gives me
Compilation options:
with_debug:     no              with_opt:       yes
with_warn:      no              with_profile:   no

Library options:
enable_shared:  no              enable_static:  yes
with_rpath:     yes             with_double:    yes

Optional libraries:
with_qhull:     no              with_csa:       yes
with_freetype:  no              with_pthreads:  no


Language Bindings:
enable_tcl:     no              enable_itcl:    no
enable_cxx:     yes             enable_f77:     yes
enable_java:    no              enable_python:  no
enable_octave:  no

The fortran examples make good postscript files. Haven't figured out 
how to do the equivalent of the command line options -dev xwin 
-drvopt defvis without modifying the source.
