Requirements for chan_gtalk & chan_jingle in 1.4beta2

I would like to know exactly which dependencies Asterisk 1.4beta2 has for enabling the chan_gtalk and chan_jingle channels. I know that in the past to get Jabber/Jingle working it required the iksemel libraries to be on the machine at compile time, but then I have read where they are not now. Anyone know for certain?

According to the link
svn.digium.com/view/asterisk/tru … iew=markup
gtalk does depend on iksemel module as of now
