Comment(by blb@…):

 This updates the libraries in ${prefix}/lib/R/lib to have the full path
 encoded, as otherwise anything which wants to link to R would need to have
 a DYLD environment variable set to see it properly.  This initially came
 up due to ticket #18784.

 The files in RHOME/library/*/libs are .so files so I'm guessing they are
 dlopen()'d right?  If so, they don't need a path encoded since dlopen() is
 going to need a full path prior to even touching them.

 As far as upstream, I'm guessing this won't happen since it seems like
 they want R to be easily relocatable by default, hence this would seem to
 be somewhat MacPorts-specific.
