What template are you using.

Adding requires statements just says that this functionality is
required by the configuration. It does not automagically cause the
requirements to be fullfilled. To do that you need to add packages to
the configuration. In this case, you need packages "CYGPKG_ERROR" and
"CYGPKG_ISOINFRA".

Most templates include these, so im surprised you don't have
them. Hence the question as to what template you are using.
