Comment 7 for bug 520986

Tie::IxHash does look like a useful way to handle this internally. That module's licensing is "same terms as Perl itself", which is an option of Artistic or GPL, and intltool is GPL also. Therefore, it seems permissible to include the module code directly in intltool itself. The Tie::IxHash module is just a single .pm file (~400 lines of code), so could just bundle that file with an appropriate installer directive (or maybe only do it conditional on the system not't have the module already available?). Or else just copy the code into directly into intltool-extract.in.
