Log Message:
* NetBSD's (and most likely Linux's) indent program is sufficient for ORBit,
  so don't depend on devel/gindent on these two platforms.

* USE_BUILDLINK2 implies AUTOMAKE_OVERRIDE=NO.

* Don't use the hackish test for libwrap supplied in the configure script.
  Instead, just specify the necessary variables to link against libwrap
  in the package Makefile.
