I spoke with upstream about this. Its currently not possible as cacao
needs to access some internals of boehm-gc which are not exposed in a
public API. Its about handling signals. Upstream plans to make it
possible to use the the system installed boehm-gc but that will need
some more work on cacao upstream.
