The Intel C++ compiler is called icpc, not icp.
Is this a typo on your message, or on the actual configure options?

If you really did "make clean" you may have removed useful things.
What did you do, "make" or "make clean"?

Which compilation tests you are talking about?
From Amber or from the OpenMPI example programs (connectivity_c and
hello_c), or both?

To get the right Intel environment,
you need to put these commands inside your login files
(.bashrc or .cshrc), to setup the Intel environment variables correctly:
and perhaps a similar one for mkl.
(I don't use MKL, I don't know much about it).
If your home directory is NFS mounted to all the computers you
use to run parallel programs,
then the same .bashrc/.csrhc will work on all computers.
However, if you have a separate home directory on each computer,
then you need to do this on each of them.
I.e., you have to include the "source" commands above
in the .bashrc/.cshrc files on your home directory in EACH computer.
Also I presume you use bash/sh not tcsh/csh, right?
Otherwise you need to source iccvars.csh instead of iccvars.sh.

The permissions here are not a problem.
You are supposed to *source* the files, not to execute them.
If you execute them instead of sourcing the files,
your Intel environment will *NOT* be setup.
BTW, the easy way to check your environment is to type "env" on the
shell command prompt.

Hard to tell in which computer you were when you did this,
and hence what it should affect.
You man have sourced twice the mkl shell that sets up the MKL
environment variables, which would write its library path more than
When the environment variables get this much confused,
with duplicate paths and so on, you may want to logout
and login again, to start fresh.
Do you need MKL for Amber?
If you don't use it, keep things simple, and don't bother about it.

Jody helped you run the hello_c program successfully.
Try to repeat carefully the same steps.
You should get the same result,
the OpenMPI test programs should run.

If you are talking about Amber,
you would have to tweak the Makefiles to tweak the linker -rpath.
And we don't know much about Amber's Makefiles,
so this may be a very tricky approach.
If you are talking about the OpenMPI test programs,
I think it is just a matter of setting the Intel environment variables
right, sourcing the ifortvars.sh iccvars.sh properly,
to get the right runtime LD_LIBRARY_PATH.
