Well, if you want to, you can also update the system-provided X11  
server here: http://xquartz.macosforge.org

That way you don't have to worry about different X servers on the  
system.  The +system_x11 variant has actually nothing to do with the X  
server.  It is just used to determine which X11 LIBRARIES are used  
when building applications.

That's not true.  I'm doing almost all development on my G5 box, so I  
assure you that Leopard/ppc is a very well tested X11 environment.   
Heck, I now have firefox-3.1b3 running with plugins for video, audio,  
and pdfs provided by mozplugger on my ppc box.

What do you mean by "apple x11 path"?  Did you enable the +system_x11  
variant?  What is the output of:
port list installed | grep xorg
...

My guess is that you probably mixed and matched building some packages  
with and some without the variant.  Bad things happen then.

Well, you linked xpdf against X11 libs in /opt/local/lib, then deleted  
them by adding the +system_x11 variant.  You need to unset that  
variant and reinstall all the ports that you installed with that  
variant, then reinstall them.

That's a pkg-config package name.  It's looking for libX11.

Why didn't it run?  Was this the libXt bug that I fixed about a month  
ago?

yes, that is what got your system in this borked state.

I'd recommend this if you're on Leopard:

rm -rf /opt/local
Install http://xquartz.macosforge.org
Install Macports
sudo port -v selfupdate
sudo port -v install xpdf

be happy.

That's correct.  Some apps look for the pkg-config files.  It's a PITA  
to support the old monolithic X11.  If you're on Tiger, your best bet  
is to NEVER THINK about using system_x11 unless you intend to live  
with or fix all the bugs you're gonna run in to.

As mentioned, it's al ok workaround for most ports, but you can't  
casually switch between that variant being on and off without  
rebuilding your system.
