I'm looking for FOSS OLAP solutions that would be easily integrated with 
Ruby (especially with an existing RoR project).
So far my luck in searching has been limited to java tools such as 
mondrian ROLAP server and JPivot or OpenI (which look like fine tools, 
but I'd prefer to stick to ruby and C)

Any knowledge of a C library that could be used as an ruby OLAP ext.  
would be very helpful also.  Thanks.
