Does -rpath not help ?

man ld
  -rpath dir
           Add a directory to the runtime library search path.  This  is  used
           when  linking  an  ELF  executable with shared objects.  All -rpath
           arguments are concatenated and passed to the runtime linker,  which
           uses  them  to locate shared objects at runtime.  The -rpath option
           is also used when locating  shared  objects  which  are  needed  by
           shared objects explicitly included in the link; see the description
           of the -rpath-link option.  If -rpath is not used when  linking  an
           ELF   executable,   the   contents   of  the  environment  variable
           "LD_RUN_PATH" will be used if it is defined.

Or is this another problem? -rpath is added in /usr/ports/Mk

> However, at runtime, it links against the system libstdc++:

I ran into this with two of my own ports. -rpath needed to be passed to ld.
