APR-1 Apache upgrade problem

I face a problem when i want to upgrade apache form 2.2.14 to 2.2.16.
When the upgrade is running the running stop at apr-1
than this step save my life.

It wasn't clear to me, but, in the end I uninstalled apr1, and then let the 'apache install' reinstall it. Here's the sequence that worked for me

pkgdb -F;portsclean -CDD;portsnap fetch update
cd /usr/ports/www/apache22
make deinstall clean
portupgrade -f -o devel/apr1 devel/apr
cd /usr/ports/devel/apr1
make deinstall clean
cd /usr/ports/www/apache22
make install clean
