Just thought someone might like to know this -
I've downloaded and enabled conditional_fields via drush, but the configuration page was not accessible, nor was there a menu entry for it at admin/structure/dependencies.
I uninstalled the module and re-enabled it via the regular admin interface, and it seems to work fine now.

Can confirm this. Happens with Drush 5.4, Drupal 7.23 (minimal install profile).

Just downloading via drush also fails:

$drush dl conditional_fields
File conditional_fields-7.x-3.x-dev.tar.gz?date=1352724212 is corrupt (wrong md5 checksum).
