Re: lang/python27: (patch) RPATH breaking build with previous installed python27

[Dustin Marquess <dmarquess%gmail.com@localhost>]

To use DT_RUNPATH, you have to use --enable-new-dtags along with
--rpath or LD_RUN_PATH.

I agree that having DT_RPATH higher priority than LD_LIBRARY_PATH was
an idiotic thing.  Luckily Linux (and probably Hurd, since it also
uses glibc) are the only OSs I know of that do this.
