>Description:
On Haiku OS, failed to create wrapper script due to missing hard link support: 
http://dev.haiku-os.org/ticket/1879

In pkgsrc/mk/wrapper/bsd.wrapper.mk line 503:
  ${LN} -f $$wrapper ${.TARGET}

It' the only one using hard link in pkgsrc framework.
>How-To-Repeat:
Use pkgsrc on Haiku (or other OS or filesystem not support hard link).

>Fix:
Even if I changed "${LN} -f" to "${LN} -sf", it works for me.
I'm not sure that hard link is really required on certain environment.
