14 This is something that should only be done on a case-by-case basis, as
15 needed -- for instance, with virtual/krb5 only one provider can be
16 installed at a time as they block eachother.
17
18 We could leave it up to portage to error on mit-krb5 and heimdal being
19 forced into the installation despite blocking eachother, but i think
20 portage would have a better chance telling end-users about the
21 conflict (and maybe helping to resolve it better via --autounmask?) if
22 there was a REQUIRED_USE.
