On an ubuntu trusty system,
* I installed v9.1.0 and could bring up a single node cluster with it.
* I did a git checkout of v9.1.0, followed by ./autogen.sh; ./configure; make
Then when I try to run for example the rados I just built using
"./src/.libs/rados -v"
I get
./src/.libs/rados: symbol lookup error: ./src/.libs/rados: undefined symbol: _ZN8librados20ObjectWriteOperation9copy_fromERKSsRKNS_5IoCtxEmj
which decodes to
librados::ObjectWriteOperation::copy_from(std::string const&, librados::IoCtx const&, unsigned long, unsigned int)
Is there any reason why this symbol should not be resolved by the installed libraries of v9.1.0?

Sounds like you've got a pre-9.1.0 librados getting loaded. This is one
of the ABI breakages that's fixed in the infernalis branch, but didn't
make the rc. This is the fix:
