Attempting to emerge mythtv with use=perl resulted in this warning during configure: WARNING: disabling Perl bindings; missing XML::Simple and no perl bindings. I added XML-Simple to the deps for use=perl and it worked.
Please attach a full log of your failure. While it may be that adding a dependency fixed your problem, the real reason for the dependency may be deeper nested.
Also, emerge --info for mythtv would be helpful. Currently I can only assume you're building with USE="-xmltv", as USE="xmltv" could unintentionally hide this problem :)
