Hi -- yes we are!  You're not the only one who's wanted versioned shared
libs, so this would be a welcome addition.  Let me look back at your
message (8/8/11, "soname support" I believe).  I apologize for the lack of
response last year; SCons wasn't getting a lot of love right around then
for various reasons.

Looking back at it, I have a few comments.
 1. it'll need documentation.  We can help with that, though if you could
rough it out that would be helpful.
 2. it'll need tests.  Is that something you could work on?
 3. There are some places where you substitute vars earlier than they
normally would be substituted, which might cause subtle bugs -- e.g.
$SHLINKFLAGS gets substituted right when the user calls
VersionedSharedLibrary, rather than at build time.  There are SConsish ways
around this.
 4. (minor) I'd prefer names like shlib_pre_action_target to
shlib_pre_action_output (at least if I understand the code correctly)

Maybe the best way forward is to start a branch for it?

(By the way, I was pretty sure we had a ticket for this in our Tigris bug
tracker, but can't find anything related right now.)
