yes, it appears that option (together with the code it controlled) was
removed/rewritten in commit fadad10632f50b122fe95e0a0cf50bdda1045a85
(from 2014-07-17).

If the server is still printing the message about
OSG_ENABLE_OGL_VERTEX_ATTRIB_FUNCS it is definitely using a different
set of OpenSG libraries - the code producing that message was part of
what was rewritten.

Those should not be related, I think.

You could try running with environment variable LD_DEBUG=libs to get the
runtime linker to print information about where it loads libs from - see
man ld.so for other settings.
