Having trouble with ZMySQLDb with Plone 4.0.4 on Windows - mysql

Question

I'm installing ZMYSQLDA for Z MYSQL Databae connection through buildout.
Here are my initial definitions:
parts=
.....
zmysqlda
[zmysqlda]
recipe = cns.recipe.zmysqlda
target = ${productdistros:location}
It seem ok, does build the instance and site works.
For information I have already installed MySQL_python throught exe file so I''m able to import MySQLdb.
When I introduce Products.ZMySQLDA in the eggs it tries to fetch MYSQL-python. I don't understand why since it's already installed.
Buidout log is
Unused options for buildout: 'eggs' 'download-directory'.
Updating productdistros.
Installing instance.
Getting distribution for 'MySQL-python==1.2.3'.
install_dir C:\Program Files\Plone 404/buildout-cache/eggs\tmparsmo9

It's trying to install mysql-python because the one you've already installed is not on the buildout's PYTHONPATH.
I would start by removing the 'target=' option in the [zmysqlda] section. You really shouldn't be pointing anything at 'productdistros' these days. It may just be that buildout can't find zmysqlda's dependencies in 'target'. If that doesn't solve it, rerun the buildout with the -vv option and post the results here.
However, as long as you're using sqlalchemy anyway, why not use the SQLAlchemyDA which plays well with it...? Then you just need to add Products.SQLAlchemyDA (and the MySql db adapter - which I presume you have for sqlalchemy anyway) to the eggs list, and you don't need anything corresponding to the [zmysqlda] part.
