error making tests

$ make g++ -I.. -Wall -O2 -llapack linear.model.test.cpp -o linear.model.test In file included from ../cppbugs/mcmc.deterministic.hpp:21, from ../cppbugs/cppbugs.hpp:21, from linear.model.test.cpp:4: ../cppbugs/mcmc.specialized.hpp: In member function ‘double cppbugs::MCMCSpecialized<double>::mean() const’: ../cppbugs/mcmc.specialized.hpp:68: error: using ‘typename’ outside of template

error seems to be here:

What's your gcc version?

I have: warmstrong@krypton:~/dvl/c++/mcmc/CppBugs/test$ g++ --version g++ (Debian 4.6.2-9) 4.6.2

When I remove 'typename' I get this:

So I think this issue was resolved with gccc 4.6
