myself.

an dir,

  ./configure --prefix=/usr/local
--with-iODBC=/usr
--with-mysql-path=/usr/local/mysql
--disable-shared
--enable-gui=no
--host=i686-apple-darwin8.8.1

it success ,but when i execute make it gave me an error

In file included from MYODBCUtilAllocDataSource.c:21:
MYODBCUtil.h:43:22: error: odbcinst.h: No such file or directory
make[1]: *** [MYODBCUtilAllocDataSource.lo] Error 1
make: *** [all-recursive] Error 1
