OK. Sorry for overlooking this.

No luck. I have recompiled all form with ffc 0.3.4.

I'm no C++ boffin, but it seems to me the the linker (g++) is getting
confused over the fact there is code in the form headers that has been
compiled multiple times (once for each class that uses the particular
form)  . Did libtool do a better job at figuring this out? How do I use
libtool?
