if 'ant' (not libant1.6-java, the package 'ant') does not work out of
the box, you should read the bug reports from ant and if there is no
one corresponding to what you think your bug is related to, you can file
a bug against 'ant'.

I think I understand it well. I don't say it's a bad idea. I say
software should not use ENV_VAR to run.

It'll be a charm to package, go a head ;-)

That's also what I did. Note that if you use libant1.6-java, you can
launch ant with a JRE... it's enough. You'll have to tell
- -Dbuild.compiler=jikes or another compiler (not 'modern' as it is the
non-free one)
