Bug#782317: python-ffc: ffc fails to compile form

[Johannes Ring]

Package: python-ffc
Version: 1.5.0-2
Severity: important

When running the following simple Python code:

    from ffc import *
    from ufl import *
    cell = triangle
    domain = Domain(cell)
    element = FiniteElement("Lagrange", domain, 1)
    jit(element)

I get this error:

    In instant.recompile: The module did not compile with command
'cmake -DDEBUG=TRUE .', see
'/home/johannr/.instant/error/ffc_form_ad8651f17820c7cc28343fcca78e8dad635a26be/compile.log'
    Traceback (most recent call last):

The contents of the compile.log file is the following:

    -- The C compiler identification is GNU 4.9.2
    -- The CXX compiler identification is GNU 4.9.2
    -- Check for working C compiler: /usr/lib/ccache/cc

    CMake Error at CMakeLists.txt:12 (INCLUDE):
      include could not find load file:

        /usr/local/share/ufc/UseUFC.cmake


    -- Found SWIG: /usr/bin/swig (found version "2.0.12")

    See also "/tmp/tmpiEIblR2015-4-10-12-15_instant_e4dc7d6e60382e59a8964429d236d1b86d91eda0/ffc_form_ad8651f17820c7cc28343fcca78e8dad635a26be/CMakeFiles/CMakeOutput.log".

The problem is that /usr/share/ufc/UFCConfig.cmake points to
UseUFC.cmake under /usr/local/share/ufc instead of /usr/share/ufc. I
will upload a new package that fixes this problem.
