+If you want to make a static build (i.e. a single, monolithic
+executable that you can just copy to another machine), then do not
+configure --with-shared.  Also, when building, you must set the
+STATIC_BUILD environment variable.  As in
+
+  $ STATIC_BUILD=1 make install
+
+The SConstruct.in file is set up for static builds on my laptop.  The
+reference lapack and blas libraries both define xerbla_, which causes
+static links to fail, so I have petsc use Atlas' lapack and blas.
+Also, when I configured PETSc, I did not include X.  Including X
+requires lots of other things that complicate the process.  In
+summary, I configure PETSC with the line
+
+  $ ./config/configure.py --prefix=/home/boo/cig/petsc --with-x=0 --with-blas-lib=/usr/lib/libblas-3.a --with-lapack-lib=/usr/lib/liblapack-3.a
+
+To make static builds on your machine, you may have to edit
+SConstruct.in to set appropriate library paths and extra libraries.
