Scalaris?
Looks good on paper, my first try results in
Crash dump was written to: erl_crash.dump
init terminating in do_boot()
without any understandable error message. Should try CouchDB.
PS: Rebuilding everything on Debian from source. We’ll see
PPS: Didn’t help :-(
PPPS: CouchDB won’t compile, it’s not finding an Erlang kernel header file. This is why I love Java and hate C. I forgot how painful compiling and installing builds with make and .h-files was.
PPPPS: Found a version which did compile. Java API doesn’t work.
PPPPPS: Back to MySQL which works. There seems a lot work needed to dethrone MySQL
PPPPPPS: Tried the same with Ubuntu 8 without success

I had no problems installing CouchDB 0.8.1 on Ubuntu 8.04. I just followed the instructions in the CouchDB README file, which boils down to :
apt-get install build-essential erlang libicu38 libicu-dev libmozjs-dev \
libcurl4-openssl-dev
./configure
make
sudo make install
And while CouchDB is still young and missing a feature or two, I think it rocks and will eventually dethrone relational databases as the web app data store of choice.
