After pulling the latest changeset, I get the following error when
building:

scons: *** [dolfin/swig/dolfin_wrap.os] Error 1
scons: building terminated because of errors.

The problem is obviously that dolfin_wrap.cc needs to be regenerated
after an interface change. Why is this not detected by the build
system?

Having to touch dolfin.i was one of the annoyances with the old build
system.

Even that didn't help. I had to remove dolfin_wrap.cc. Then
dolfin_wrap.cc is regenerated and everything works fine.

How can this be fixed?
