On every modern distribution, or better said, on every distribution
but LFS you have depsolver tools that automatically cater for the
dependencies, no one is on "treasure hunts" since ages. For Fedora
Core take your pick:

     smart install dovecot
     yum install dovecot
     apt-get install dovecot

On FC1 it yields the following:

# smart install dovecot

12.9MB of package files are needed. 32.7MB will be used.

Confirm changes? (Y/n): 

That's all there is to "treasure hunts".

You got an error message because you explicitly broke package and
library dependencies, you want such a breakage to be the default mode
of packaging and library management? Sorry, that's totally

I'm a Fedora/Red Hat user and in a parallel thread a gentoo user and
myself were making distributions jokes. But to be honest I like
gentoo, if I were to use source based distribution, I would go gentoo.

From what you write *you are a gentoo user*, but possibly don't know
that yet. If you need taylored, minimal setups tuned to your liking
and matching your demands and your hardware you need to use gentoo
(or other similar distributions).
