sieve-dev FIAT import question

[Jed Brown]

When I try to build the sieve examples, I get errors like the one below.  If I
move the `import FIAT.shapes' up to the top of the file, it works just fine.  I
don't know if there is something peculiar about my configuration, but this
problem hasn't gone away in the last weeks so I thought I'd mention it.  My
configuration included the options:

--with-fiat-dir=/home/jed/usr/lib/python2.5/site-packages/FIAT --with-fiat=1

but the error persists with --download-fiat=yes instead.

Traceback (most recent call last):

On another note, the bratu example will work much better with the following one
character fix.
