Might be best to unset LD_LIBRARY_PATH

I believe I've posted instructions on this several times in the past.

Assuming that you have cc in your PATH and the CC=cc

A. For Bourne/Korn Shells

   1. For Sun's Forte compiler
      CC=cc  CPPFLAGS='-D__EXTENSIONS__' CFLAGS='-xarch=v9a'  \
        ./configure <args-to-configure>

   2. For gcc 3.x or better

      CC=gcc CPPFLAGS='-D__EXTENSIONS__' CFLAGS='-m64' \
        ./configure <args-to-configure>

B. For Csh and derivatives

   1. For Sun's Forte compiler
      setenv CC       cc                 \
      setenv CPPFLAGS '-D__EXTENSIONS__' \
      setenv CFLAGS   '-xarch=v9a'       \
        ./configure <args-to-configure>

   2. For gcc 3.x or better

      setenv CC       gcc                \
      setenv CPPFLAGS '-D__EXTENSIONS__' \
      setenv CFLAGS   '-m64'             \
        ./configure <args-to-configure>

The CPPFLAGS='-D__EXTENSIONS__' is necessary because configure doesn't
(yet) include <crypt.h> and crypt gets the wrong prototype in a 64-bit
application, leading to a SIGSEGV in swat

If you experience difficulties linking some shared objects, it's
because the definition of SHLD doesn't include CFLAGS. The workaround

make SHLD='${CC} ${CFLAGS}' 

when building Samba

You could also use '-xarch=v9' or 'xarch=v9b' for UltraSparc III or
'-xarch=native64' instead of '-xarch=v9a'
