Many people do this error, I do not understand why.  Only source 
packages must be uploaded, not binary ones!!  Moreover, the binary 
packages must be created in pbuilder, not in packager's or user's 
day-to-day partition!!  About one year ago there was a post on debian 
lists giving this as a recommandation, I do not know how this was continued.

This solves all the problems.

Libraries are automatically added in build-depends.  Only the header 
might be missing.
