That's a good reason... and one that hopefully can be fixed.
As I'm sure you know, .dylib files are the Mach-O (link format used
by OS X) equivalent of ELF .so files. The main difference is that
.dylib files have a bit more meta data and can contain multiple
architectures, so they need to be created with the right set of tools.
You can use "libtool -dynamic", just like most platforms, or "gcc
-dynamiclib" to do it directly from the compiler. This works well
enough with the amalgamation:
$ gcc -dynamiclib sqlite3.c -o libsqlite3.dylib
You can also embed version information and some meta info into the
.dylib file. If you have cross compilers installed, you can create a
.dylib file that has both Intel and PowerPC object code, although
that's becoming less and less important.
If you want to take this off-line, I'd be happy to help with more
specifics.
