Mutt-devel problem, maybe headers-cache

[Sbranzo]

Maybe someone could help me with mutt-devel.
After forcing portindex update I was trying to port upgrade mutt-devel
but:

sudo port upgrade outdated

This is the current installed version:
$ port installed mutt-devel
The following ports are currently installed:
mutt-devel @1.5.14_1+db4+headercache+imap+pop (active)


Maybe I'm overlooking something trivial.

Thanks,
