You should be able to run two LDM-s on the same system -- each listening for 
connections on any interface -- simply by having two different LDM user 
accounts and building one using the default port and the other using a 
different port via the "--enable-port=..." configure(1) option (as you did). 
We've done that here with complete success.

The ldmping(1) utility of the "enable-port=38888" should only try to connect to 
port 38888 and not port 388 -- so it shouldn't be confused.
