It would be good to know how you installed gfortran, since it is not working
(see below).

This means that g++ is not installed, which will be a problem. [Developers:
note that configure is failing to give a reasonable error message here when
there is no g++ in the PATH.]

This is now essentially a fatal error. You can Google on "libmpc.so.2" and
see if any of the many posts about this seem to be relevant. If you post the
exact commands you used to install the compilers, it might help. Also, you
might want to consult
http://ambermd.org/ubuntu.html to see which things need
to be installed. [Developers: can we update this page to more recent
releases, and to more flavors of Linux?]

Having flex is certainly a good idea.
You will certainly need to fix the gfortran problem before trying to continue.
...good luck...dac
