What I do with CamelBones is include a number of binary "support 
bundles" with the main framework. Each one of these is built and 
linked against a specific version of libperl. These support bundles 
entirely hide the libperl API, and expose a public API that is 
consistent regardless of the libperl version in use. The main 
CamelBones framework examines the host system when it's initialized, 
and dynamically loads the correct bundle.
