I'm following this How-to on installing MySQL on Snow Leopard but instead of using MySQL 5.1 I'm downloading the source for MySQL 5.5.11

so when I go into the source directory and run:

```
./configure --prefix=/usr/local/mysql --with-extra-charsets=complex \
--enable-thread-safe-client --enable-local-infile --enable-shared \
--with-plugins=innobase

```

I get:

```
-bash: ./configure: No such file or directory

```

What am I missing? what am I doing wrong?
