Pirouet, I ran into the same error when I tried to install D 6.1 as well.

As a quick-fix, I opened v61.sql (under the <dolphin root folder>/install/sql)and changed line 8881 from:

`Control` enum('select','checkbox','radio') collate utf8_unicode_ci NOT NULL default 'select' COMMENT 'input element for selectors',

to


`Control` enum('select','checkbox','radio','') collate utf8_unicode_ci NOT NULL default 'select' COMMENT 'input element for selectors',

Essentially, I just added see more '' as a option to the list of options in the enumeration for the 'Control' field.

I haven't looked in detail to see if this can have an adverse effect in the application elsewhere, but for now, the installation should proceed smoothly if you make that change.

I hope this helps..
