I believe this thread explains what happens:

http://lists.fedoraproject.org/pipermail/devel/2010-January/129148.html

Now, because internal Boost uses threads by default, libcutl links
to -lpthread. And this leads to what is described in that mailing
list post. I am trying to confirm this on FC17 right now.

In the meantime, you can build libcutl with threads disabled (ODB
does not use threads) by passing the --disable-threads configure
option. I believe this will fix the issue.
