A bundle is MacOS lingo for a standardized package directory, for example, and app [1].

So if doing an app, one possibility is static linkage, but one can also use dynamic linkge and include the library. For example, the LilyPond does that, specifically contains both the dynamic .dylib and static .la.

It is one of several MacOS package managers. It installs stuff in /use/local/ but more or less requires one changing permissions of this director to single user.
