[plt-scheme] connecting DrScheme servlets to MySQL

I'm using DrScheme v299.100.  I want to connect with a MySQL database.  
I had some adventures with mysqlclient.ss below.  Then I thought, 
"Maybe I should be using SchemeQL and/or SrPersist?"  SrPersist is 
available for the early 2.0x PLT Schemes.  Can/should I use it?  Where 
should I be going?  Thanks.

-----------------------------------

I'm new to mzc.  I downloaded mysqlclient.ss from:  
http://www.cs.uvm.edu/~dvanhorn/scheme/
I put the files c-syntax-transformer.ss c-syntax.ss mysqlclient.ss in:  
~/lib/plt/mysql/
I wrote a little foo.sh:

-----8<-----
#!/bin/bash

MZC=/Applications/Added_Apps/PLT_Scheme_v299.100/bin/mzc
LIB=/usr/local/mysql/lib/libmysqlclient.a
INC=/usr/local/mysql/include/
WHAT=mysqlclient.ss

$MZC --auto-dir ++ldf $LIB ++ccf -I$INC $WHAT
-----8<-----

which produces the errors below.  What am I doing wrong?
