We have a tarball of the source available:

paramotopy-1.0.3.5.tar.gz

Building from source has the following dependencies:
  • Bertini, both the parallel executable program, and the serial library.
  • Boost.Filesystem, Timer, System, Chrono, Regex.
  • GMP.
  • MPFR.
  • MPI. Recommended: MPICH2.
If you are using a Mac, consider using Homebrew to install the dependencies, where possible.
Paramotopy is not currently offered in pre-compiled binary form. Sorry! If you need help compiling from source, please don't hesitate to send email to the authors for assistance. We use the autotools for compilation, so ./configure, make, make install pattern is in full effect here.

Also, if you have knowledge of how to portably compile so we can distribute executables without inducing library hell on our users, advice is welcome.
You probably should be aware of the license. Paramotopy is free to read and use, but not for modification and redistribution. This is similar to the current terms of Bertini's license.
