Getting to know Merb

I'm reviewing the code base for merb and have noticed the following:

Hyphens and underscores are intermixed as word separators
Modules seem to be structured like Perl (a note about Ruby, actually)
Are assets only javascript and css files? In movabletype they are media content files, like images, audio, and the like
I like that the docs include a README file in many places, written in Markdown format - nice!
Slices appear to be what I call extensions in Nexista, sort of like mini-apps
I've heard good things about datamapper, but I'm still a little uneasy about ORM, I just really like SQL!
I'm interested in merb-core, merb-exceptions, merb-gen, merb-slices, and merb_datamapper

So, off to a slow start in comprehending the library code, so now I'm going to try installing merb and building a quick app.

To install merb on debian, I'm doing the following:

apt-get install libsqlite3-dev
apt-get install libextlib-ruby1.8

OK, now this:

dev-48-gl:/var/www/dev# gem install merb
 Building native extensions.  This could take a while...

What do I do now? I tried calling "merb" but that didn't work. Hmmmm.... ah! Have to use the full path /var/lib/gems/1.8/gems/merb-core-1.0.12/bin/merb (or add it to PATH).

I'm looking for merb-gen though, here it is:

Looks like some making / compiling is going on. Do I have rake installed? No, I installed it. Running rake in the testmerb directory reveals this:

$ rake

Oh yeah? Well how about this?

sudo apt-get install libdataobjects-ruby1.8 libdataobjects-sqlite3-ruby1.8 libdataobjects-mysql-ruby1.8

No? How aobut this?

sudo gem install dataobjects

Oh, picky, huh? Too bad, I've installed dataobjects 0.9.12. Ugh...
