fallout: tests which are written in C need to point their run-path
to the build version of the shared libraries.
o The default is shared libs with .so, except for on Darwin, where
shared libs are named differently. The Darwin part is untested.

was correct, it was mis-placed in the file. It needs to include
<elf.h> or the moral equivalent of that before the symbols can be
tested. This now corresponds with what's committed upstream.
Again, since this is a build fix, no revision bump should be required.
in no code change and adding portability to NetBSD 3.x, so no
revision bump:
o Let the workaround for missing R_PPC_ADDR16{HI,LO} work for other
systems who also define R_PPC_16_{HI,LO} instead.
o Add portability to NetBSD/powerpc 3.x, which has a very minimalist
<powerpc/elf_machdep.h> file.
fully built and installed when the build is run as root. The reason
this is problematical is that perldoc changes uid if run as root, to
either 'nobody', 'nouser' or uid -2, for security reasons, and then
cannot write files owned by root or create files in directories owned
by root with 'normal' permissions.
No revision bump as this should purely be a build fix.
Pkgsrc changes:
o New MASTER_SITES
o Take maintainership (apologies if I'm stepping on someone's toes)
o The package now has built-in knowledge if the CPU arch has working
jit support (currently i386, powerpc and arm, of which the two first
have been tested), so there's no need to direct the jit support from
the main Makefile
o Update PLIST
o Added patches to port to NetBSD/powerpc (reported upstream)
o Added patch to remove a GNUism from one of the shell scripts
(test using == in place of =)
Upstream changes:
o Too many to mention; there have been some 20-odd number of
intervening releases since the 0.4.11 release of 2007-Apr-17,
according to
http://docs.parrot.org/parrot/latest/html/docs/parrothist.pod.html
which contains the release history.

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
patch with a more tolerant version of patch (like netbsd's) gives two
copies of the definitions in the same file, with who knows what
consequences. Applying the patch with a less tolerant version of patch
fails.
So, remove it, and bump PKGREVISION just in case.
Based on patch provided in PR 36157, update to 0.4.10.
