Guidance on Ahead of Time Compilation for Mono 2.2?

Does anyone have recommendations on using ahead of time compilation for the system libraries under Mono 2.2? The Mono website has this article with some (outdated?) information about how to carry it out. I tried following the instructions with the following exceptions:

• I found multiple mscorlib.dll assemblies (at /usr/lib/mono/1.0, 2.0, 2.1) and tried AOT-compiling all of them. Only the 1.0 and 2.0 assemblies succeeded. The 2.1 assembly kept referring to the 2.0 assembly and never produced the .so file for itself.
  
• Several assemblies (System.Xml.dll for one) in the GAC failed to precompile. The AOT compilation process for that one complained that it could not load the System assembly.
  

When I tried executing Mono executables (themselves also AOT-compiled and working prior to my pre-compilation of the system assemblies), they universally failed with Mono framework errors.

Has anyone successfully AOT-compiled the system assemblies under Mono 2.2? Is this even a good idea, assuming there's a way to make it work?

Compiling Mono 2.0.1 on Ubuntu Gutsy Server 8.04

I didn't want to use the aging Mono version present in Ubuntu Server 8.04, so I set out to compile Mono 2.0 (and subsequently 2.0.1, via the same process). This turned out not to be too bad.

First, install the requisite packages:

aptitude install build-essential swig autoconf gawk mono-common binfmt-support bison pkg-config libglib2.0-dev

Yes, that's not a typo--you do want one of Ubuntu's Mono packages, mono-common. This will enable shell execution of Mono executables via ./ notation rather than having to execute "mono /path/to/executable."

Once you are done, download and unpack the source for Mono. This will get you 2.0.1:

wget http://ftp.novell.com/pub/mono/sources/mono/mono-2.0.1.tar.bz2
tar xf mono-2.0.1.tar.bz2

Now you are ready to build and install Mono (the make step will take a while):

cd mono-2.0.1
./configure --with-libgdiplus=no
make
make install

Lastly, you need one symlink so the binfmt-support package can execute Mono executables directly via the shell:

ln -s /usr/local/bin/mono /usr/bin/cli

That's it. Typing the command "mono -V" should yield the about information for Mono 2.0.1. Follow the instructions under "Testing the Mono installation" and confirm you can not only build and execute the example.exe application, but that you can execute it with ./ notation (e.g. ./example.exe).

Cheers!
