compiling using native compiler

[SS]

When I try to compile python 2.3.4 using SGI's native compiler 
./configure --without-gcc
followed by
make

I get error
make
         c++   -o python \
                        Modules/python.o \
                        libpython2.3.a -ldl  -lpthread -lmpc   -lm
ld32: WARNING 84 : /usr/lib32/libdl.so is not used for resolving any symbol.
ld32: FATAL   9  : I/O error (-lmpc): No such file or directory
collect2: ld returned 32 exit status
*** Error code 1 (bu21)

but I see it in /usr/lib

ls -l /usr/lib/mpc
-rwxrwxr-x    1 root     sys       598996 May 20 17:10 /usr/lib/mpc
