Quite right this is a problem, and it looks like something we should fix before 6.4.1. I'll give it some thought. Cheers, Simon On 24 August 2005 14:42, Duncan Coutts wrote: With our current 6.4.1 snapshot 20050819, we have problems building when we've got more than over version of

Re: mysterious directory include error

Works for me with a 6.4.1 snapshot. I've upgraded to 6.4.1.20050903 and it still doesn't work. Did you remember to create the empty directory 'foo'? Of course, I think there are two things wrong: (1) the fact that it doesn't work, (2) the fact that the error message is uninformative.
