Xorg, XFree on netbsd/alpha

[Robert Dörfler <rodo%zlug.org@localhost>]

Hi,

i just installed NetBSD5.1 on my AlphaPC 164LX some days ago.When i was
starting X i realized that its not the usual xorg/xfree86.Its 
XdecNetBSD. I'm just wondering why its included on the iso-distribution.
Isnt there an usual xorg/xfree86 package around for alpha?

Greetings,

Robert
