new Centos server install yum dependancy error

[Voytek Eymont]

I'm installing a new Centos 7 server, following repo.dovecot.org/ page,
but, get this:

(I've opted to install all BUT pgsql (use mysql), not sure I really need
all other packages..?)

should I just go for "dovecot dovecot-mysql dovecot-pigeonhole" ??

tried
# yum install dovecot dovecot-debuginfo dovecot-devel dovecot-imaptest
dovecot-imaptest-debuginfo dovecot-lua dovecot-mysql dovecot-pigeonhole
dovecot-pigeonhole-debuginfo dovecot-pigeonhole-devel

...

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
