multiple definition abgcdp, adgcdp, dpgcdp

Hi all. I am installing ncl_ncarg-5.0.0 on the front end node (fen) of
our IBM Blue Gene/L (SUSE Linux with powerpc chip). I get these messages
during the build

(when it's trying to build the executable named "ncl"):

: multiple definition of `abgcdp'

: multiple definition of `adgcdp'

: multiple definition of `dpgcdp'

 Here is the excerpt from a transcript of my build:

************************************************************************

The e.g. abgcdp multiple definition evidently arises because of the
following in libnfpfort.a (specifically the sg_tools.f contribution to
that library ):

DOUBLE PRECISION FUNCTION ABGCDP (AQDP,BQDP,CQDP)

 in addition to the following in libhlu.a (the SphericalGeometry.c
contribution):

double abgcdp(double*,double*,double*);

That is to say, the functions have the same names in the two libraries.
But I expected the following to deal with that, which is in the NCL

"INSTALL.txt" file:

*********************************************************************

If, however, your compiler does not append an underscore (the IBM
xlf/xlf90 compilers are

two such examples), then you need to set this macro as follows:

    NgCallF reg

********************************************************************

Regarding that, I had confirmed earlier that the $NCARG/config file that
the build will use is "LINUX":

SYSTEM_INCLUDE = "LINUX"

and NgCallF is in fact set correctly in that file:

*******************************************

cd $NCARG/config

grep Ng LINUX

#define NgCallF reg

******************************************

So I'm puzzled by the multiple definition error, I would have thought
"NgCallF reg" would have attended to the issue. Can you help?

I've googled this but can't find anyone who has obtained these
particular multiple definition errors.

Note: I'm building everything to run on the fen, not the compute nodes,
i.e. I'm using native compilers, not cross compilers. I'm doing a 32-bit
architecture build.

Also, I'm using the IBM compilers, e.g. xlf and xlc. And finally, the
'tmpnam' warning in the excerpt above is a warning and I doubt it is the
cause of the exit of the build.

My complete LINUX file is as follows:
