question about db4 installation

Hello,
I have tried to install subversion via darwinports with no success. My
main hangup is the db4 installation. The syserr/sysout output of the
command "sudo port install db4" is as follows:

--->  Fetching db4
--->  Verifying checksum(s) for db4
--->  Extracting db4
--->  Configuring db4
--->  Building db4 with target all

<new lines removed>

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_dports_databases_db4/work/db-4.3.29/build_unix"
&& make all" returned error 2

It seems there might either be:
1. A problem with the db4 port.
2. A missing library, or a library that is installed but cannot be
found by the linker.

I'm guessing the port is ok, and its a lib issue :)

Can anyone point me toward a solution?
Thanks,
John
