Error libxml2 after uninstall Proxy Server with mod_security

[jok]

Hello.
I am testing pfsense 2.02 in a virtualized enviroment before put it in production, and I need to remove the package Proxy Server with mod_security. When I remove this package and reboot, the system don't start and give me libxml2 missing errors. In this case, I restore an snapshot and no problem, but I want to remove this package.
Some suggestion?
Thanks!

remove the package and then from the shell run pkg_add -r libxml2

Or backup your config, edit out the bad package, reinstall from an iso, then restore your config
