apache pkgsrc binary unstable on NetBSD 5.2

[Donald Lee <MacPPC2%caution.icompute.com@localhost>]

I've installed the relevant 5.1 packages on my newly upgraded 5.2 test system.
The OS upgrade - boot from CD, upgrade, reboot - is almost flawless.
(nice job. ;-> )

Unfortunately, I seem to have hit a bug.  It looks to me like this is the
one: bug: lib/39986

Symptoms:
Errors in the apache error log precede a crash and failure of apache.  It
won't stay up.

>/usr/pkg/lib/php/20090630/zlib.so: Trying to call undefined weak symbol 
>`__deregister_frame_info'

It looks like this is fixed in 5.2, but there are no package binaries for
5.2, only 5.1.

I'm still looking for a fix.  An option, in theory, is to re-build those
misbehaving packages on my 5.2 system.  I have therefore downloaded
pkgsrc, and am trying to build some, starting with devel/zlib.

When I do "make readme" on pkgsrc, I get tons of these:

Shared object "libarchive.so.3" not found

Am I doing something stupid, or does pkgsrc have some dependency on
6.0? (I think libarchive.so.3 is in 6.0)

Is it reasonable for me to re-build those packages that are misbehaving
to fix my apache stability problem, or am I putting effort down
a rat-hole?

Another fix for me would be to use packages built on 5.2.  Are there plans to
do that?

Thanks for any help,
