Thanks for your quick answer.
According to http://rpm.org/wiki/PackagerDocs/Dependencies#ScriptletDependencies
Using "Requires(pre)" would be a hack (in the sense of "it's not
designed for this"), wouldn't it ?

I think it's more safe to consider modifying 'bar' package in order to
make it depends of 'foo'

Thanks for your help,
