MySQL installation in Snow Leopard Server appears to be broken?

Question

I tried
sudo gem install mysql -- --with-mysql-config=/usr/bin/mysql_config
and it failed.
The mkmf.log said (in part):
"gcc -o conftest -I. -I/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/universal-darwin10.0 -I. -DXOPENSOURCE -DDARWIN_CSOURCE -I/usr/include -fno-omit-frame-pointer -pipe -DP1003_1BVISIBLE -DSIGNALWITH_VIOCLOSE -DSIGNALSDONT_BREAKREAD -DIGNORESIGHUPSIGQUIT -arch x86_64 -g -Os -pipe -fno-common -DENABLE_DTRACE -fno-common -pipe -fno-common conftest.c -L. -L/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib -L. -arch x86_64 -pipe -L/usr/lib -lmysqlclient -lz -lm -lruby -pipe -L/usr/lib -lmysqlclient -lz -lm -lpthread -ldl "
ld: library not found for -lmysqlclient
collect2: ld returned 1 exit status
checked program was:
/* begin */
1: /top/
2: int main() { return 0; }
3: int t() { mysqlsslset(); return 0; }
/* end */
So, I checked mysql_config:
Usage: /usr/bin/mysql_config [OPTIONS]
Options:
--cflags [-I/usr/include -fno-omit-frame-pointer -pipe -DP1003_1BVISIBLE -DSIGNALWITH_VIOCLOSE -DSIGNALSDONT_BREAKREAD -DIGNORESIGHUPSIGQUIT]
--include [-I/usr/include]
--libs [-pipe -L/usr/lib -lmysqlclient -lz -lm]
--libs_r [-pipe -L/usr/lib -lmysqlclient_r -lz -lm]
--socket [/var/mysql/mysql.sock]
--port [0]
--version [5.0.91]
--libmysqld-libs [-pipe -L/usr/lib -lmysqld -lz -lm]
Note that mysql_config appears to have been compiled with an assumption that /usr/lib
would contain a -lmysqlclient shared library.
Which assumption fails on my Snow Leopard Server installation:
minisvr:~ root# ls -la /usr/lib/mysql
ls: /usr/lib/mysql: No such file or directory
Now, I'm reasonably certain that I have done nothing to cause this library to be missing;
as I am also reasonably certain that the mysql_config found in /usr/bin is one shipped by
Apple (as opposed to one I could have picked up somewhere else).
Can anyone else out there verify: does Apple ship /usr/bin/mysql_config?
If so, does it supply linker options like -L/usr/lib -lmysqlclient?
If that also is true, does your /usr/lib actually contain an Apple-supplied libmysqlclient.*?
Now, assuming that my installation is reasonably close to what Apple actually shipped,
what should I do about it? Would I be better off to go find a source distribution,
and build and install mysql, foregoing the Apple-supplied integration with
management tools (e.g., using Server Manager to start/stop and monitor logfiles)?
What do other users of mysql on Mac OS X Server do?
Thanks,
