Oh, right, there was a whole subthread about this issue already... BernieC: Please link to previous threads if they're related.

t/02_basic.t ........... 1/85 POSIX::tzset not implemented on this architecture at blib/lib/SVG/TT/Graph/TimeSeries.pm line 582, <DATA> line 593. # Looks like your test exited with 255 just after 72.

If all you did was try again, nothing has changed. My Pull Request has not been merged yet, no new releases have been made. If you want to run this now make the same edit I did. https://github.com/ranguard/svg-tt-graph/pull/31/files, note line 582. Perhaps a simple way to do this is to run look SVG::TT::Graph within a cpan session, this will download the latest release and drop you into a shell. Edit lib/SVG/TT/Graph/TimeSeries.pm as per the link above then run cpanm ..

The author has merged the pull request and a new version of SVG::TT::Graph hit cpan 6 hours ago.

I saw that. Version 1.03 checked in yesterday. But:

I see that Martin updated both SVG::TT::Graph and SVG::TT::Graph::XY and SVG::TT::Graph::TimeSeries. I wanted to check out SVG::TT::Graph::TimeSeries by itself and cpan is making me crazy

cpan> install SVG::TT::Graph::TimeSeries
Warning: Cannot install SVG::TT::Graph::TimeSeries, don't know what it
+ is.
Try the command

    i /SVG::TT::Graph::TimeSeries/

to find objects with matching identifiers.

cpan> i /SVG::TT::Graph::TimeSeries/
No objects found of any type for argument /SVG::TT::Graph::TimeSeries/

What did I do wrong this time?

One more PR merged, a mistake on my part, not the module author. Expected a new release.
