It appears to be missing a dependency on XML::Parser (dev-perl/XML-Parser?):
checking for XML::Parser... configure: error: XML::Parser perl module is required for intltool
The output of `emerge -pqv '=x11-libs/vte-0.34.9::gentoo'`:
[ebuild NS ] x11-libs/vte-0.34.9 [0.28.2-r206] USE="introspection -debug -glade"

emerge --info '=x11-libs/vte-0.34.9::gentoo'
Actually this might be a mix of it and me:
1. The ebuild seems to lack the dependency on the perl module, but the configure does check for it. This seems to be a bug.
2. However, something seems to also be wrong with my system, as XML-Parser is installed:
Can't locate XML/Parser.pm in @INC (@INC contains: /etc/perl /usr/local/lib64/perl5/5.16.3/x86_64-linux /usr/local/lib64/perl5/5.16.3 /usr/lib64/perl5/vendor_perl/5.16.3/x86_64-linux /usr/lib64/perl5/vendor_perl/5.16.3 /usr/local/lib64/perl5 /usr/lib64/perl5/vendor_perl /usr/lib64/perl5/5.16.3/x86_64-linux /usr/lib64/perl5/5.16.3 .) at - line 1.
% equery f dev-perl/XML-Parser
Google-ing a bit, and I found `perl-cleaner --modules`; this seems to be what I need to run, and after running it the ebuild is now proceeding just fine, as I already have XML-Parser.
