  なぜかは分かりませんが、libz.soがリンクされていないのが原因でした。
  そこで、perl Makefile.PLが生成するMsql-Mysql-moduleのmysqlサブディ
  レクトリのMakefileのリンクパラメタに -lz を書き加えてmake,make test
  してやり、正常に動作する mysql.soが作成されました。

Which drivers do you want to install?

    1)  MySQL only
    2)  mSQL only (either of mSQL 1 or mSQL 2)
    3)  MySQL and mSQL (either of mSQL 1 or mSQL 2)

    4)  mSQL 1 and mSQL 2
    5)  MySQL, mSQL 1 and mSQL 2

Enter the appropriate number:  [3] 1


Do you want to install the MysqlPerl emulation? You might keep your old
Mysql module (to be distinguished from DBD::mysql!) if you are concerned
about compatibility to existing applications! [n]
Where is your MySQL installed? Please tell me the directory that
contains the subdir 'include'. [/usr/local/mysql]
Which database should I use for testing the MySQL drivers? [test]
On which host is database test running (hostname, ip address
or host:port) [localhost]
User name for connecting to database test? [root]
Password for connecting to database test? [undef]
