::__cap_get_proc() has always returned ENOSYS in the base system (indicating
::that it was not implemented), as we never committed the implementation of
::the system call. It looks like your binary is picking up cap_get_proc()
::from libc, which suggests your libc isn't in sync with the source tree,
::since libc no longer contains cap_get_proc(). It may be that zsh's
::autoconf picked up on the library calls (now removed), and built in a
::dependency on them. You might need to rebuild zsh to work around this
::once libc is rebuilt.
I realized that my world was not in sync, just after I send out my e-mail.
Thank you for feed back, anyway. :-)
I hope my original e-mail would be a small heads-up for the rest of
zsh users, who may get into same kind of trouble. :-P
Thanks,
Haro
