SVR4/sparc emulation setup from Solaris 7 media

[Joe Abley <jabley_(_at_)_patho_(_dot_)_gen_(_dot_)_nz>]

I just found my Solaris 7 media in a drawer, and thought I might be able
to pull the necessary bits and pieces off it to get SVR4 emulation
running on my OpenBSD 2.6/sparc box.

Couple of very quick questions:

1. Has anybody managed to get SVR4/sparc emulation running with
libraries whipped from Solaris 7? I presume there's no fundamental
reason why Solaris 7 libraries would be inferior to any other
Solaris release's, as far as OpenBSD/SVR4 emul goes?

2. Could anybody point me at a reference for how Solaris packages
work? I've been trying to figure it out, but the only files under
the SUNW* directories I can find that look big enough to be packge
archives are compress(1)ed ELF binaries.

I'll keep plugging on, but if anybody could give me a pointer or two
on those it'd be appreciated.
