[SAC-HELP] sac on 64-bit SMP box

[Derek]

Hi,

I'm hoping to install sac on a linux box running 64bit SMP linux

        >uname -a
        
        Linux localhost.localdomain 2.6.15-1.1833_FC4smp #1 SMP Wed Mar
        1 23:55:52 EST 2006 x86_64 x86_64 x86_64 GNU/Linux

but, in reading the archives of this mail list, it seems SAC won't work
in 64-bit mode, and indeed, when I compile the source version I have
(05Mar01.sac.tgz), it fails.  Although, it seems to fail because it
can't find or can't make a proper X11 library:
        
        [snip from "make" output]
        cc -w -DLINUX -o ../bin/sac \
        main/sac.o ../lib/sac.a ../lib/libevresp.a ../lib/libSMnonOracleFuncs.a ../lib/libSacOracleStubFuncs.a   -L/usr/X11R6/lib -lX11 -lm -lnsl -ldl
        /usr/bin/ld: skipping incompatible /usr/X11R6/lib/libX11.so when
        searching  for -lX11
        /usr/bin/ld: skipping incompatible /usr/X11R6/lib/libX11.a when
        searching for -lX11
        /usr/bin/ld: cannot find -lX11
        collect2: ld returned 1 exit status
        make[1]: *** [SAC] Error 1
        make[1]: Leaving directory `/usr/local/sac/src'
        gmake: *** [all] Error 2

Can any one tell me if I should request a 32-bit binary, or if there is
a way to compile it to make it work?

Thanks,
