--- Comment #7 from olelukoie olelukoie@mail.ru 2012-10-07 12:55:57 CDT --- Well... I've made some more testing and found that libosmesa is not really needed for Civ3 to work. At least it's not needed with current wine 1.5.14+.
So if you do not want to change the configure script you can close this bug with any resolution you like.
