As an experiment, I have built a Mac OS 10.5 installer package (x86 32bit) which I have also placed there. Took a bit of fiddling about to discover how to use PackageMaker and how to automate it. It's built to work against Apple's Perl and Java, which have 32bit runtimes. Time permitting, I will later look at how to do a fenced plugin which would enable using an external language plugin of a different architecture. No guarantees - YMMV. If it works, enabling the Perl and Java stored procedure plugins should be as simple as :
~$ mysql -u root
