Re: Strange problems using libmysequoia with Carob 3 beta / Ruby

Hi Csaba,

Thanks for the quick reply. There's no particular reason I'm using the 
3.0 beta, other than that it was already in beta 2 and there seemed to 
be significant differences in the config files, so I thought I may as 
well use it so that I don't have to convert the whole setup when 3.0 
final comes out.

I'll try out the CVS version and if that doesn't work, I'll move to the 
previous stable version of Sequoia.

Thanks again for your help!
Paul
