 Josh,[[br]]
 In r75626 I increased the revision of ports listed by 'port echo
 depends:poppler' as well as ports installed on my computer which include
 links to libpoppler.7.dylib.[[br]]
 If additional bugs are caused by links to libpoppler.7.dylib let me
 know.[[br]][[br]]
 Cheers,[[br]]

 P.S. If indirect dependents are known to link to libraries which they do
 not directly depend upon, might it be helpful to explicitly include those
 libraries in depends_lib (or depends_lib-append) to reduce the need for
 otool-script-based investigation?
