[Dovecot] Pigeon hole sieve binaries and dovecot header install

Stephan,

I've recently been playing around with packaging dovecot 2.0 and dovecot-2.0-pigeonhole, as well as the --enable-header-install configure options of both. This lead me to the following question. Should pigeonhole's sieve binaries rely on static libstorage / other dovecot libraries? It seems like they should instead use shared libraries, but I couldn't find a configure option to make this happen.

That way, I could break my packages up like so:

dovecot dovecot-devel libdovecot dovecot-pigeonhole dovecot-pigeonhole-devel

And while pigeonhole/sieve might require libdovecot to run, it shouldn't require it to compile.

Thoughts? I can provide a lot more detail about my compilation errors if you think its necessary.
