I can give you some clues.  The problem lies in the definition of the
IOPT macro, which is defined in cipe/cipe.h.  The stock cipe.h defines
IOPT as
    #define IOPT(c) (&(c)->sock->inet)

That's OK for older 2.6 kernels, but newer kernels require
    #define IOPT(c) ((c)->sock)

The 2.6.14 patch (assuming you're talking about my 2.6.14 patch)
changes the definition and wraps the change in a test of the kernel
release:
    #if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,12)
    #define IOPT(c) (&(c)->sock->inet)
    #else
    #define IOPT(c) ((c)->sock)
    #endif

(I'm not sure 2.6.12 is the correct branching point for this change,
but that won't affect kernels later than 2.6.12.)

It appears that
    - You applied some patch other than mine, or
    - Your build is picking up another cipe.h, or
    - Your build is finding a kernel build directory for an older
      release

For CIPE to live on, it needs someone or some group to step forward
and take on maintenance.  For awhile I thought I might be in a
position to do that, but my life took a different turn.  I believe
there is now a project to maintain CIPE, based on SourceForge I think.
