building packages for other NetBSD releases

[Jukka Salmi <j+nbsd%2007.salmi.ch@localhost>]

Hi,

I need to build packages for NetBSD 3 and 4 systems on a -current
NetBSD system (all of them i386). So far I've been doing this by setting
up chroot environments using NetBSD 3 and 4 sets on the -current system
and using pkgtools/libkver inside these chroots. That's probably similar
to what pkgtools/pkg_comp does, though I've never used pkg_comp.

This used to work fine until the newlock2 branch was merged to NetBSD's
HEAD. Since then, building e.g. the OpenLDAP packages doesn't work
anymore:

$ cd databases/openldap-client && make
[...]

openldap-client-2.3.32
=> Modifying GNU configure scripts to avoid --recheck

=> Replacing config-sub with pkgsrc versions

*** Error code 1

I [1]posted the relevant part of the failing configure program to
current-users some weeks ago.

So, what's the "supported" way of building packages for other NetBSD
releases on a NetBSD system? Or is this considered to be a bug in
OpenLDAP configure script's thread detection?
