I get the following error:

mpicxx -o main.o -c -Wall -pipe -ansi -g -Werror -O2 -fno-strict-aliasing
-pthread -DDEBUG -DNDEBUG -DHAS_MPI=1 -DMPICH_IGNORE_CXX_SEEK

sh: mpicxx: command not found
scons: *** [main.o] Error 127
scons: building terminated because of errors.

because I use a local installation of PETSc (that downloads mpich).
should the PETSc path be added to PATH in dolfin.conf? since DOLFIN picks up the
compiler from PETSc?

Currently my SConstruct looks like this:

import commands
import os

# Use system PATH since I don't have mpicxx in default path
env = Environment(ENV = {'PATH' : os.environ['PATH']})

# Get compiler from pkg-config
compiler = commands.getoutput('pkg-config --variable=compiler dolfin')

# Update CXX compiler
env.Replace(CXX = compiler)

# Get DOLFIN cflags and libs 
env.ParseConfig('pkg-config --cflags --libs dolfin')

# Build program
env.Program('demo', 'main.cpp')

which is not too elegant but it works.
