Where are you getting these file sizes? Perhaps you need to strip(1) the
binaries?

I'm not sure what this means. If you mean the mono binary, you need to strip(1)
it; on OS X, it's 4.1MB.

You need to strip(1) this binary. On OS X, libmonosgen-2.0.1.dylib is 4.2MB.
Also note that the `mono` binary doesn't require libmono*.so; it statically
links it in. libmono*.so is for embedding use.

Where are you getting this file size? On OS X, the 4.5 mscorlib.dll is 2.9MB.
For example, consider mkbundle(1):
http://docs.go-mono.com/?link=man%3amkbundle(1)
mkbundle(1) can be used to bundle all assemblies into a single file, to
simplify distribution. Using mkbundle(1), you can have a single native binary
which only requires libmonoboehm-2.dylib to execute, no additional assemblies,
by using `mkbundle --deps`:
$ AS='as -arch i386' \
CC='cc -arch i386' \
PKG_CONFIG_PATH=/Library/Frameworks/Mono.framework/Libraries/pkgconfig \
mkbundle --deps -z hw.exe -o hw2
$ ls -lh hw2
-rwxr-xr-x+ 1 jon staff 1.0M Nov 24 10:53 hw2
$ nm -ufm hw2

With the above setup, "Hello world" requires "only" ~5.2MB of disk to run (for
OS X binaries).
