Building External Functions on an IRIX64 system

[Cyndy Chandler <cchandler@xxxxxxxx>]

Help!
I'm trying to build some Ferret external functions on an SGI system.

% uname -a
IRIX64 synthesis 6.5 01101245 IP27
% ferret
        NOAA/PMEL TMAP
        Program FERRET  
        Version 5.22 - 08/23/00
        26-Sep-01 12:52     

I'm trying this just to compile one of the Fortran modules:
       f90 -O -o scat2ddups.o scat2ddups.F

and getting:
ld32: WARNING 85: definition of __q_sign in
/usr/lib32/mips4/libfortran.so preempts that definition in
/usr/lib32/mips4/libftn.so.
ld32: WARNING 85: definition of s_cat in /usr/lib32/mips4/libfortran.so

ld32: WARNING 85: definition of b_pad in /usr/lib32/mips4/libfortran.so

ld32: WARNING 85: definition of s_copy in /usr/lib32/mips4/libfortran.so

ld32: Bus error.  Removing output file...
ld32: INFO 152: Output file removed because of error.
f90 INTERNAL ERROR:  /usr/lib32/cmplrs/ld32 returned non-zero status 1
*** Error code 1 (bu21)

I figure the WARNINGS are OK, but
ld32: Bus error.   ???

I've tried various combinations of ENVar settings, including:
#    CC='/usr/bin/cc -64'
#    CPPFLAGS=-DNDEBUG
#    CFLAGS=-O
#    FC='/usr/bin/f90 -64'
#    FFLAGS=-O
#    F90='/usr/bin/f90 -64'
#    CXX='/usr/bin/CC -64'
#    CXXFLAGS=-O

Can anyone help me with this?  
Perhaps if someone had a 
$FERRET_STUFF/ext_func/src/ef_utility/platform_specific_flags.mk.irix64
type of definition file?  The iris4d version didn't work on my system.

Thank you,
Cyndy
