i think you're merging the two issues you brought up ... there is binary ABI 
issues (which should not require a new DEPEND variable as portage can extract 
that information out at runtime) and there is runtime plugin issues with 
packages using dlopen() (which portage cannot extract as the dependency 
cannot ever be extracted)

or did i not read your original e-mail incorrectly ?
