You can't run the cyrus services by hand (they're made to run under the 
cyrus master only). You can somehow include a debugger for one of the 
services, I'd try that on lmtp. Are you sure that you've preforked a 
lmtpd? The error message you've sent could also result from 1) user id 
problems (postfix piping as nobody, cyrus running as cyrus for exemple) 
or 2) dissension about where the lmtp socket is between deliver and 
lmtpd.

BTW: when you've fixed this problem, you may want to consider using 
postfix's lmtp client as it will probably be faster (one fork less, 
because in your current setup, you'll fork pipe which will call the 
deliver program).

Hope that helps,
Baltasar
