Is this a clean 6.0 system, or an upgraded one?  If you built inside
a chroot, did you remember to upgrade the chroot to 6.0 userland as
well?  If you're using binary packages, did you remember to update
the PKG_PATH variable or pkgin's repositories.conf to look at a 6.0
repo?

I've seen something similar before just after upgrading and installing
my first newly built binaries.  This probably means that some component
(either the end-point binary or one of the libraries it loads),
was linked to libpthread.so.0 (the 5.x libpthread) and one or more
of the other libraries (or the binary itself) was linked against
libpthread.so.1

NetBSD 6.0 has a newer libpthread and needed to bump the ABI version,
and libpthread can only be active once when the program is started,
and all binaries using .so-files that use it need the library linked
into it.  libpthread is a bit odd that way ;)

This can be debugged by using ldd(1) on the binary and working through
all its .so-files, recursively running ldd on them.  One of those
should eventually show up being linked against libpthread.so.0; that
needs to be rebuilt and reinstalled.

Hope this helps,
Peter
