Indeed, configuring sqlite to compile as a dylib on OSX is easy (it's the default).
I think what Richard may mean is packaging an installer so that the dylib is installed where it needs to be. As you point out Jay, dylibs have additional metadata, part of that is the full path to the dylib, and this is also in the sqlite program. So the dylib needs to be installed where it was compiled to be - /usr/local/lib. It is possible to set DYLD_LIBRARY_PATH, like LD_LIBRARY_PATH on Linux, but Mac users don't want to be bothered by this. Using a static library means the sqlite program can be installed whereever the user likes, as long as they know how to run it (ie it's in their PATH). No admin permissions needed. With a dylib, the program can still be anywhere, but the dylib needs to be where the program expects it, normally in /usr/local/lib, which needs admin permissions. Either a script to copy it there could work (again, there's the issue of us being Mac users), or a Mac installer package is needed.
