OpenBSD developers do not support pkgsrc.

I cannot recommend using the NetBSD port of Xorg either.. OpenBSD has it's own X port called Xenocara, which includes local security changes.
Why did you revive this old thread? are you still using 4.3/4.3? if so.. they are unsupported, 4.6 is due out next month.
