Hi,

I have a problem installing mysql ruby gem on 64bit CentOS machine.

[jacekb@vitaidealn ~]$ uname -a
Linux vitaidealn.local 2.6.18-92.el5 #1 SMP Tue Jun 10 18:51:06 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

Mysql and mysql-devel packages are installed. Mysql_config provides following paths:

Usage: /usr/lib64/mysql/mysql_config [OPTIONS]
Options:
    --cflags         [-I/usr/include/mysql -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fno-strict-aliasing -fwrapv]
    --include        [-I/usr/include/mysql]
    --libs           [-L/usr/lib64/mysql -lmysqlclient -lz -lcrypt -lnsl -lm -L/usr/lib64 -lssl -lcrypto]
    --libs_r         [-L/usr/lib64/mysql -lmysqlclient_r -lz -lpthread -lcrypt -lnsl -lm -lpthread -L/usr/lib64 -lssl -lcrypto]
    --socket         [/var/lib/mysql/mysql.sock]
    --port           [3306]
    --version        [5.0.45]
    --libmysqld-libs [-L/usr/lib64/mysql -lmysqld -lz -lpthread -lcrypt -lnsl -lm -lpthread -lrt -L/usr/lib64 -lssl -lcrypto]

Trying to install:

[jacekb@vitaidealn ~]$ gem install mysql -- --with-mysql-include=/usr/include/mysql --with-mysql-libs=/usr/lib64/mysql
...
ERROR:  Error installing mysql:

I would appreciate any help. Thanks for reading :).
