I'm having trouble with pydolfin when umfpack is installed. I'm pretty 
sure the reason is that umfpack is a C library, which is why I get the 
below undefined symbol error.

Somehow, I think
  extern "C"
needs to appear in the SWIG files somewhere as a prefix to the umfpack 
functions. I've tried a few things without luck. It takes an age to 
rebuild the SWIG interface, so I'm not getting far with stabs in the 
dark. Any ideas what should be done?
