Funnily, I use OmniOS myself, but the Schily tools were not installed there just yet.

In theory, this should work (requires wget and GCC for me, Clang does not work well yet):

shell wget https://sourceforge.net/projects/schilytools/files/schily-2021-05-19.tar.bz2/download tar xjf download cd schily-2021-05-19 make # this can take a while pfexec make install # optional
