Subject: AMBER: problem of installing carnal on macosx

I tried to install the carnal program in amber7 on my Mac OS X Tiger. got the
following error when i type "make install" :

/usr/bin/ld: Undefined symbols:
_fprintf$LDBLStub
_printf$LDBLStub
_scanf$LDBLStub
_fscanf$LDBLStub
_sprintf$LDBLStub
_sscanf$LDBLStub
collect2: ld returned 1 exit status
make: *** [carnal] Error 1

By searching on internet i found that the problem is related to the confliction
of gcc4.0 and g77 on my computer. So i changed it to use gcc3.3.

lawn-128-61-118-177:~/amber7/src/carnal root# gcc -v
Reading specs from /usr/libexec/gcc/darwin/ppc/3.3/specs
Thread model: posix
gcc version 3.3 20030304 (Apple Computer, Inc. build 1809)

lawn-128-61-118-177:~/amber7/src/carnal root# g77 -v
Reading specs from /usr/local/lib/gcc/powerpc-apple-darwin7.9.0/3.4.4/specs
Configured with: ../gcc/configure --enable-threads=posix --enable-languages=f77
Thread model: posix
gcc version 3.4.4

But i got the same error message as above. And i found there is suggestion of
append -lSystemStubs to LIBS line, but there is no LIBS line in the Makefile.
Any suggestions for this problem? Thanks in advance.
