how to change the default charset with GBK or other language of mysql ??

[Ka]

I install a mysql server in default installation with latin charset, but
I want to use GBK(a chinese charset), so that I can store and
search chinese words directly.

so, I download, unpack and then rewrite the mysql.spec and then recompile
the
package mysql-3.23.56-1.80.src.rpm.

first, this file contains some files:
[root@a root]# rpm2cpio mysql-3.23.56-1.80.src.rpm |cpio -t
filter-requires-mysql.sh
my.cnf
mysql-3.23.51-manfixes.patch
mysql-3.23.56.tar.gz
mysql-errno.patch
mysql.init
mysql.logrotate
mysql.spec

so, I rewrite the mysql.spec with
../configure \
--with-charset=gbk\
.......

and then cp all file into /usr/src/redhat/SOURCES/
#rpmbuild -ba /usr/src/redhat/SOURCES/mysql.spec

all compile is okay,
but the binary test can not be passed, why ? does it fail in charset=gbk???
and following is the part of output :

+ make test
cd mysql-test ; ./mysql-test-run
