I see, thanks for bringing that up. To clarify (I hope this is): Gentoo Prefix tries to be as much self-sufficient as possible, and hence applications *must* not reference the host system, unless absolutely necessary, such as for e.g. /lib/libc.so. If Gentoo Prefix would not do this, Portage's dependencies would become useless, and many uncontrollable and unpredictable errors may arise both at compile time as well as at run time. -- Fabian Groffen Gentoo on a different level
