Cleaner how? Seems to me they are equivalent, but #2 takes a lot less setup, no?

You may want to look at how datapump handles this in 10g. If memory serves (queue the Iron Chef music), datapump now uses the same syntax as 'create user identified by values 'HASH');

I see two ways to accomplish this:
1. use Datapump to export the database links.
     PARFILE would look something like this:

    you can then use datapump to import into your dev database.

2. I did a quick test of this with a database link and it worked.
      select name,userid,passwordx,host from$;

   I then constructed a create statement:
create database link <name> connect to <userid> identified by values '<passwordx>' using '<host>';
   I was able to use the link.

I think method 1 is a lot cleaner, however.
