Problem with DB44 on Intel MacBook Pro

[Steven Rogers]

I'm setting up several things using MacPorts per this page:

http://blog.duncandavidson.com/2006/04/sandboxing_rail.html

and I get an error when I get to subversion:

sudo port install subversion +tools
Password:
--->  Building db44 with target all
Error: Target com.apple.build returned: shell command " cd "/opt/ 
local/var/db/dports/build/ 
_opt_local_var_db_dports_sources_rsync.rsync.darwinports.org_dpupdate_dp 
orts_databases_db44/work/db-4.4.20/build_unix" && make all " returned  
error 2
[ . . . snip . . . ]

and there are other comments in the page reporting a similar error.  
However, when I do:

port clean db44

port install db44 +universal +darwin_8

Then it builds OK. I'm building on an Intel MacBook Pro running  
10.4.10  - I don't know MacPorts well enough to tell what's going  
wrong. Hopefully someone can figure it out.

Thanks,
