According to the mysql forums you must compile with

./configure --prefix=/usr/local/mysql --with-charset=cp1251 --enable-thread-safe-client --with-max-indexes=256

unfortunately there does not appear to be a way to change after compiling

Seems like the message is clear... YOu can't have a table with more than 64 keys (Primary, Foreign or even index)
