I can confirm this bug on Fedora 17. The problem as you mention, is that
configure is not checking for/adding pthread to the LIBS variable. This
used to be fine, since pthread is already required by other libraries used
by Stk. However, it's now required to explicitly link against it. i I've
attached a patch to configure.ac. You'll have to regenerate configure with
autoreconf for it to work:

patch -input=configure.patch
./configure
make
cd projects/demo
make libdemo

Good luck!

Best,
Tristan

And here's the result of the link error  that I'm seeing.
