Yeah, I understand how it can happen, and I've even seen it on a
Solaris box. But Scott's message seems to imply that partially
statically linked binaries work right now, and that we need to
keep it that way moving into the next release, even at the expense
of potentially breaking fully dynamic binaries. Perhaps he meant
 My initial thought was that FreeBSD did something differently
such that this could work in FreeBSD but not in Solaris, but
I just tried it and this is not the case.
