www.elasticworld.org (it is a new interpreted programming language with
a lot of features [real closures, oo-programming, i like to call it
"a python with what's missing from python"...])

maybe you're right. if i can't find a better soulution i'll go for
static linking. the problem is that the api changes, but is not
backward-uncompatible, so a shared library would be fine.

with --release:
libelastic-0.0.15.so
with --version-info:
libelastic.so.14.0.1
(note that if the api changes, next version will be):
libelastic-0.0.15.so or libelastic.so.15.0.1
