Presumably `gem install` would install files directly into the prefix,
bypassing the destroot. We would not want that. Figure out how to get `gem
install` instead to install into the destroot; root permission should not be
needed to do so.

Set
build.asroot yes
in the portfile, but that is not the proper solution for this case. Setting a
phase's asroot property to yes should not be needed in the vast majority of
cases.
