Thanks for looking into this.
It's very well possible that the comment is wrong, since I'm no RPATH expert 
and just wrote down what I observed. I also tried to get some comments about 
how it should behave. also on FreeBSD, but without luck.
So if you think libraries should also have the complete RPATH, then this 
should be handled exactly like for executables.
One thing: on "make install" the libraries will be relinked with the new 
install-RPATH, so this will take some more time.
That's actually one of the reasons why I didn't add the RPATH to the 
libraries.
