I confess that I never attempted to seek on an IO::Handle when I was writing for perl 5.10, but I am currently attempting to release a package that includes this action and I would like to verify support back to 5.10. I get the title error in my travis-ci tests (with the container based Debian). Any thoughts on how to get around this? I suspect some incremental support occurred from 5.012 onward and that there is a known way around it for perls 5.010 and earlier but I'm unable to find it with a search. I would appreciate any suggestions.
