latest xorg port compiles but does not run on sparc64

Hi. I'm not sure what exactly is the correct mailing list for these 
things, since it applies to both -current, -sparc64 and -ports, so I 
thought I would try -current first. Sorry if this is inappropriate.

Anyway, I recently got hold of an old Sun Ultra10 which I upgraded from 
6.2-RELEASE to -CURRENT (dated about midnight, 7 feb). At that time no 
ports were installed.

Then I proceeded to build and install the xorg-server port 
(xorg-server-6.9.0_6) manually, but it wouldn't run. On startup of X the 
rather curious message appeared:

dlopen: /usr/X11R6/lib/modules/fonts/libbitmap.so: Undefined symbol 
"xf86stderr".

Unfortunately I forgot to make a typescript, so I can't tell if something 
went wrong during the build. Building xorg on an ultra10 takes several 
hours, so please forgive me for not building a second time. Meanwhile I 
got X running using binary packages.

Does anyone have any clue as to what might have happend? The full Xorg.log 
is reproduced below.

Cheers
Michiel
