I want to upgrade ActivePerl and my Perl Dev Kit. What's available?
You may have already seen the announcement... Last year, ActiveState announced that the direction for the company's future will be OpenSource Languages.
Proprietary tooling for certain languages is not part of the OpenSource Languages Company future. Sales of both of the Dev Kit tools sets were discontinued at the time of those announcements. New licenses for PDK and TDK will not be available as separate products.
Engineering and Development time and resources were immediately priorized for updating the existing language distributions. In 2017, work is starting on the new languages. Work was stopped on PDK, and that means that there will not be a PDK 9.6.
Existing copies of PDK 9.5.1 cannot use the latest releases of ActivePerl. The 2203 and 2204 builds are not compatible, and all 5.24 versions remain incompatible with the final release of PDK 9.5.1.
2202 is the last compatible ActivePerl, except on OS X.
For OS X, the 9.5.1 release of PDK was created on OS X 10.5. Every PDK must have a 100% binary compatible ActivePerl. ActivePerls switched from building on OS X 10.5 to building on OS X 10.9 at 220.127.116.112 and are now 64-bit only. These two factors are responsible for the unresolvable symbols error message. Since there will not be a 9.6 that is also built on OS X 10.9, the 2201 release is the last ActivePerl that is compatible.
