Problem with IMP

[Chojin]

Horde Versions
Horde: 1.3.5-cvs
IMP: 2.3.7-cvs
Turba: 0.0.3-cvs

When I try to access to IMP it says:
The XML functions are not available. Rebuild PHP with --with-xml.
but I compiled PHP with it:
'./configure' '--with-apxs=/usr/local/sbin/apxs'
'--with-config-file-path=/usr/local/etc' '--enable-versioning'
'--with-system-regex' '--disable-debug' '--enable-track-vars' '--without-gd'
'--without-mysql' '--with-gd=/usr/local' '--with-ttf=/usr/local'
'--with-zlib' '--with-mcrypt=/usr/local' '--with-imap=/usr/local'
'--with-mysql=/usr/local' '--with-ldap=/usr/local' '--with-openssl=/usr'
'--with-snmp=/usr/local' '--enable-ucd-snmp-hack' '--with-xml=/usr/local'
'--enable-ftp' '--with-curl=/usr/local' '--with-gettext=/usr/local'
'--enable-sockets' '--enable-sysvsem' '--enable-sysvshm'
'--enable-trans-sid' '--prefix=/usr/local' 'i386--freebsd4.3'

What is the problem then ?
