Debian is not supported by the PathScale compiler. It might
be possible to get it to run... ;-) on the most recent "Debian
etch" but I am sure it is untested.

See Section 2: Table 2-1 Supported Linux Distributions and Platforms

        Red Hat Enterprise Linux 4 (RHEL4)
        Fedora Core 3, 4, 5 (FC3, FC4, FC5)
        SUSE Linux Enterprise 10a
        SUSE Linux Enterprise Server (SLES) 9
        SUSE Linux Professional 9.3

The Pathscale compiler itself is a 32bit object.
There are two versions of Debian etch,
    32bit and 64bit
which one is is being used? The new Debian etch 64bit has
minimal support for 32 bit user space programs by default. It may be
necessary to install 32 bit libs and or compatability libs to
get it to run correctly.

I do not know which gcc compiler suite Debian GCC is based on.
"gcc -v " can tell volumes. Since the PathScale compiler
uses parts of the gcc compiler suite this could be important.
In RHEL4 compare and contrast gcc4-4.1.1-53 .vs. gcc-3.4.6-8.
The Pathscale compiler is recently rebased to also work with gcc4
based systems.

Do foundation Open MPI tools like .../bin/orterun
compile and run well enough to return errors? If the Usage message
fails to print then all bets are off for MPI itself. Example:

        $ OMPIhome/bin/orterun
        orterun (OpenRTE) YourVersion
        Usage: orterun [OPTION]... [PROGRAM]...
        Start the given program using Open RTE
        ... etc.

Scan the eko man page for PathScale compiler specific options.

ompi_info does not capture compiler flags so report your
configure line, make line and environment variables.
