Ah, ok, I think I get it, now.

Ok. I think, I got that too. Sorry, I'm easily confused by these
cross-development issues and constantly mix up host and target.

There might be a misunderstanding here: the "cross-chicken" _is_ a
native chicken, but invokes cross-build-tools and links with a
target-specific library. I assume you followed the method given in the
manual (http://wiki.call-cc.org/man/4/Cross%20development). The
cross-chicken can both install and build code for the host ("native")
or target system, just pass either "-host" ("chicken-install" + "csc")
or "-target" ("chicken-install"). Target-specific installation should
probably use "-prefix" to install into the appropriate location that
holds the target-specific binaries.

So, you shouldn't need to have a separate "chicken-native"
installation. Alternatively you can configure it during build-time
("EGGDIR=...") to share the egg-repository with the (native parts of
the) cross-chicken, but this may be a bit of a hack.

I hope this is in some way helpful. I'm afraid I don't have enough
experience with OE to give a more competent answer.
