I browsed the modules modules.mk files and came across (for example dav):

mod_dav.la: mod_dav.slo props.slo util.slo util_lock.slo liveprop.slo providers.slo std_liveprop.slo
        $(SH_LINK) -rpath $(libexecdir) -module -avoid-version mod_dav.lo props.lo util.lo util_lock.lo liveprop.lo providers.lo
std_liveprop.lo

It seems the -rpath option is goodness here. Would that solve our problem?
