SH script, variable built command fails, but works at command line

I am working with a sh script on a solaris 9 zone (sol 10 host) that grabs information to build the configuration command line. the variables Build64, SSLopt, CONFIGopt, and CC are populated in the script. the script includes

Code:
CC=`which gcc`
CONFIGopt=' --prefix=/ --exec-prefix=/usr --libexecdir=/usr/lib/libexec --includedir=/usr/include --with-random=/dev/random'  
SSLopts=' --with-openssl=/usr/local/openssl-1.0.0j-pkcs11'
BUILD64=' -m64 -mcpu=v9'

./configure CC="\"${CC} ${BUILD64}"\" ${CONFIGopt} ${SSLopts}

When i run the sh -x script.sh i get the following output.
Code:
+sh ./configure CC="gcc -m64 -mcpu=v9" --prefix=/ --exec-prefix=/usr \
--libexecdir=/usr/lib/libexec --includedir=/usr/include --with-random=/dev/random --with-openssl=/usr/local/openssl-1.0.0j-pkcs11
checking build system type... sparc-sun-solaris2.9
checking host system type... sparc-sun-solaris2.9
checking for gcc... "gcc -m64 -mcpu=v9"
checking whether the C compiler works... no           <-------- FAILURE
configure: error: in `/bind-9.9.1-P2':
configure: error: C compiler cannot create executables
See 'config.log' for more details

config.log just has: configure:4078: "/usr/local/bin/gcc: No such file or directory.

BUT if I copy that command line and paste it to the prompt everything works.

if i put that expanded command line into the script, it works

NAME
sdl-config - script to get information about the installed version of SDL SYNOPSIS
sdl-config [ --prefix[=DIR] ] [ --exec-prefix[=DIR] ] [ --version ] [ --cflags ] [ --libs ] [ --static-libs ] DESCRIPTION
sdl-config is a tool that is used to configure and determine the compiler and linker flags that should be used to compile and link pro- grams, and libraries, and plugins that use SDL. It is also used internally by the m4 macros that are included with SDL. OPTIONS
--cflags Print the compiler flags that are necessary to compile a program or library that uses SDL. --exec-prefix=DIR If specified, use DIR instead of the installation exec prefix that SDL was build with when computing the output for the --exec-pre- fix option. This option must be specified before any of the --cflags, and --libs options. --libs Print the linker flags that are necessary to link a program that uses SDL. --prefix=DIR If specified, use DIR instead of the installation prefix that SDL was built with when computing the output for the --prefix, and --exec-prefix options. This option is also used for the exec prefix if --exec-prefix was not specified. This option must be speci- fied before any of the --cflags, and --libs options. --static-libs Print the linker flags that are necessary to statically link a program that uses SDL. --version Prints the currently installed version of SDL on standard output. EXAMPLES
gcc -o main.o $(sdl-config --cflags) main.c is how you might use sdl-config to compile a C source file for an executable program. gcc -o my_app $(sdl-config --libs) main.o util.o is how you might use sdl-config to link compiled objects into an executable program. AUTHOR
