Comment (by kencu):

 There is no trac ticket I know of for this; I suspected an issue, but it's
 only proven as of now, so I guess we will need  one.

 I believe we will need to bring gcc back to the non- at rpath fold for
 MacPorts in some fashion, rather than adapt MacPorts to support @rpath
 linkages for gcc/libgcc. Iain was going to give us a configure arg to
 disable @rpath, or a separate non- at rpath branch to pull from if we wanted
 that -- if those do not exist (I haven't seen them yet), then we either
 need to revert the @rpath commits (yuck) or we need to rewrite the
 libraries to have full paths on installation and possibly tweak gcc to let
 it know we did that (probably best, I believe).

 The cmake issue is probably going to become more and more of an issue
 (unless we have avoided it with our cmake PortGroup settings, which would
 be a lucky break). So far, the cmake issue is only hitting Tiger I
 believe.
