Evan,

It might depend on the way ACML has been compiled by the AMD people. Your
version of gcc/gfortran might be incompatible with ACML 4.1.0.
This is known to users and is causing  problems. You can see it reported in
the ACML forum here (it applies to 4.0.1 but I think the problems have not
been solved)

http://forums.amd.com/devforum/messageview.cfm?catid=217&threadid=90399&enterthread=y

Here I report a part of a post of that thread

Begin quote:

"The gfortran ACML libraries are currently built with two different
GCC/GFORTRAN compilers.

The SINGLE THREADED libraries found in /opt/gfortran64 and
/opt/gfortran64_int64 are built with 4.1.2. This compiler version is used
because it is the most widely supported compiler with most new linux
distributions (or was in 2007).

The OpenMP MULTI THREADED libraries found in /opt/gfortran64_mp and
/opt/gfortran64_mp_int64 are built with 4.2.0. This compiler is used because
it was finally released in 2007 and 4.1.2 does not natively support OpenMP.

This is mentioned in the release notes, but it's obvious not very clear.

When using GCC/GFORTRAN 4.3, you will likely need to use the mp versions of
the library. This has not been tested by AMD. When 4.3 releases, AMD may
provide a 4.3 build.

This issue happens because of the incompatibility between GCC 4.1.2 and 4.2.
Now that more distributions are supplying GCC 4.2 AMD may only support GCC
4.2 for 2008 releases. In other words, no more 4.1.2 builds. Both single-
and multi-threaded libraries would be built with 4.2. "
end quote

Se also subsequent replies.
Maybe you should try first to see  whether the ACML work at all on your
system apart from R.
Hope this helps

Ciao

Simone
