You can define a variable to be passed in plist:
PLIST_SUB=     ARCH=${ARCH}

and then %%ARCH%% will be available.

I guess that you’ll have to patch the Makefile…

What is the output of `ldconfig -r | grep polymake'?

On FreeBSD, if your library is libpolymake.so.4.4, you should also
install a symlink for libpolymake.so and libpolymake.so.4.
Without that, it won’t be registered in the libraries hints file.
