Who told you that?

No you don't, unless the AP is configured to work with WPA only and not WPA2.  
The latter uses CCMP.

Instead of feeling unnecessarily depressed, you may want to spend a few 
minutes studying the manual files and looking at the example or configuration 
files of applications that you intend to use:

Why do you think that wpa_supplicant does not support AES encryption?  The 
config file which is nicely commented shows:

=========================================
# pairwise: list of accepted pairwise (unicast) ciphers for WPA
# CCMP = AES in Counter mode with CBC-MAC [RFC 3610, IEEE 802.11i/D7.0]
=========================================

So to make your wireless connection work, emerge wpa_supplicant and add 
something like this in /etc/wpa_supplicant/wpa_supplicant.conf:

network={
       ssid="Rebellion"
       bssid=XX:XX:XX:XX:XX:XX  <--enter the AP MAC address
        proto=RSN
        key_mgmt=WPA-PSK
        pairwise=CCMP
        auth_alg=OPEN
        group=CCMP
        psk="ascii key goes in here"  <--use wpa_passphrase to create it
       priority=5
}


To learn how to use wpa_passphrase run:

  man wpa_passphrase 

in a terminal.


HTH.
