Newbie can't install xorg-libXext

[Rasmussen Law Offices, PLLC]

First let me say that I'm very new at using macports.

I was trying to install hydrogen on my Macbook running Leopard  
10.5.7.  It hangs when it starts to try and install xorg-libXext.

Here's the message that I get:

administrators-macbook:~ Administrator$ sudo port install -v hydrogen
Password:
--->  Building xorg-libXext
Error: Target org.macports.build returned: shell command " cd "/opt/ 
local/var/macports/build/ 
_opt_local_var_macports_sources_rsync.macports.org_release_ports_x11_xor 
g-libXext/work/libXext-1.0.99.4" && make all " returned error 1
Command output: sh: line 0: cd: /opt/local/var/macports/build/ 
_opt_local_var_macports_sources_rsync.macports.org_release_ports_x11_xor 
g-libXext/work/libXext-1.0.99.4: No such file or directory

Error: The following dependencies failed to build: scons python25 tk  
xorg-libXScrnSaver xorg-libXext
Error: Status 1 encountered during processing.
administrators-macbook:~ Administrator$

So how do I fix this?  I've tried installing xorg-libXext by itself  
and I get the same message.

Thanks for any help you can give.  Rock on.
