* I am only linking to the shared library AFAICT and I only have one
copy of "-lmongoclient". I do link to other .so's that are lso built
and linked to mongoclient however
* Mongo build produces
/usr/lib64/libmongoclient.a
/usr/lib64/libmongoclient.so
I don't link to .a but I wonder if somehow something is. I'm tempted
to remove it after building
* I made one tiny change to source to get this to compile w/my app

You might want to take a look at the first response on this thread
here: http://groups.google.com/group/mongodb-user/browse_thread/thread/2d24e6748db2978e
Looks like it may be a similar issue.
Hope this helps!

I verified i have 2 copies of the library "linked"
strings /usr/lib64/libsipXcommserver.so | grep 'Security is a
singleton class'
strings /usr/lib64/libmongoclient.so | grep 'Security is a
singleton class'
so C++ idiom to assume static vars are initialized is probably ok
(not to mention C++ documentation everywhere mention this is safe).
Libtool just isn't making it obvious it's using that static lib, so I
just need to track that down and force linking to .so.
I'll try to reply back w/workaround, as I suspect this might bite
someone else someday.

LDFLAGS = -shared
when building my library. This fixed the issue but also in turn
stopped creating static version of my library as well, however it's
just as well, because I didn't need static versions of my library.
