As Michael said, but to add a bit...

- pdo-mysql is an alternative to the regular mysql extension. When H4  
is released, any of the old mysql extension, mysqli, and pdo-mysql  
should be sufficient

- MDB2_Driver_MySQL is a pear library (php code), not a pecl package  
(C extension)

- MDB2 (and PEAR DB) will be phased out entirely by release time for H4

Right now H4 is alpha code, more or less. I'd expect dependencies to  
balloon a bit while we sort out refactoring, etc. in the new version,  
and then to tighten up again as we move towards release.
