Hi Peter,

did you check what "pkg-config --libs nettle hogweed" returns in your
environment? If you want to prefer your own libraries, I think the
simplest way is to remove nettle-devel package, unless you want to build
your own package. Environment variables PKG_CONFIG_LIBDIR and
PKG_CONFIG_PATH may help you. Visit man pkg-config. It should include -L
flag with path in --libs, if installed to non-standard path.

Cheers,
Petr
