You're probably right.  It occured to me that as my sid machine is a
PIII, it's probably looking in i686 (or somewhere else, I guess, see
below) instead of i586, which DNE.  Does anyone have evidence of this
working correctly on an i586?  

I just tried getting it to work via /usr/local/lib/i686 and, failing
that, /usr/lib/i686, but again, to no avail.  Any idea where it should
go for a P3?

open("/etc/ld.so.preload", O_RDONLY)    = -1 ENOENT (No such file or directory)
open("/etc/ld.so.cache", O_RDONLY)      = 3
open("/usr/lib/libssl.so.0.9.6", O_RDONLY) = 3
open("/usr/lib/libcrypto.so.0.9.6", O_RDONLY) = 3
open("/lib/libdl.so.2", O_RDONLY)       = 3
open("/lib/libc.so.6", O_RDONLY)        = 3
open("/usr/lib/ssl/openssl.cnf", O_RDONLY) = 3

That's identical on my sid PIII and my woody celeron.  Doesn't look like
it looks in /usr/lib/i[56]86 at all.  Can anyone show otherwise?

good times,
