OSError: /sushi/conrad/nestsampling/multinest/libnest3.so: undefined symbol: mpi_send_

HI everyone,

I have build multinest and pymultinest and specifying WITHOUT_MPI=1 with no errors but when I import pymultinest the following error shows:

OSError: /sushi/conrad/nestsampling/multinest/libnest3.so: undefined symbol: mpi_send_

any helps.

Run ldd on libnest3.so. It looks like it was compiled with MPI (mpif90 instead of gfortran).
The easiest is to try building with https://github.com/JohannesBuchner/MultiNest , it is Multinest 2.17 with a custom makefile that handles WITHOUT_MPI=1.
