Thanks DAC.
I installed serial version earlier on 32bit of same OS (ubuntu 10.04) using 32bit counterparts of these compilers. It all went perfect that time.
As of now I've turned to this 64bit system.
Though I'm working with a CPU with dual core processor. I need MPI because I intend to perform Thermodynamic Integration (TI).
Please suggest whether I'm on correct lines or not? I know performing TI requires parallel Amber 10. Is MPI required by AmberTools too?

[Scott: we are getting *lots* of reports of configure failing to correctly
figure out the g++ version or running its tests. Can you try to figure out
what might be going on? Maybe some users don't have "cut"? Maybe it doesn't
always work correctly? I'd like to get a more robust way of getting past this
step.]

This has come up before:
http://archive.ambermd.org/201007/0376.html
It seems to be some unusual conflict between our code, 64-bit compilers (of
some versions), and maybe exactly what is in 1.2 code tree.
Did this work for the serial compilation? I notice that there is a "-m64"
argument to mpicc above. If you edit config.h and remove all instances to
"-m64" does it help? (Was the -m64 there in the serial build?)
(And of course, finally: are you sure you need an MPI version of NAB? It
wouldn't make much sense to try to track down an very funny bug in an old
version of parallel AmberTools if you are not planning to use it anyway....)
