Wow, things are changing.  I guess the ldm is finding the portmapper now?  And, 
from
your first message port 388 was not in use, but now, apparently, it is.

The only reason port 388 would be in use is because a previous invocation of 
the ldm
has not released it.  Do a 'rpcinfo -p' again.  I think it will tell you that 
port 388
is in use by the ldm.  Check to see if all the ldm processes are dead ('ps -ef 
| grep
ldm').  If they aren't, kill 'em!  If they are dead but the port is still in 
use, do
'rpcinfo -d 300029' to deregister the port.  (You must do this as user ldm.)

Commenting out the 'exec pqact' in ldmd.conf is a good testing approach.  Even 
if pqact
isn't running you should still be getting products in your product queue.  You 
can test
this with 'ldmadmin watch'.  Also, you can use 'pqcat' to verify that products 
are in
the queue.

No, it is not usually the case that you must give a full path name for pqact.  
Is your
LDMHOME variable set properly?

And, no, it is not the case that root should own most of the files.  I suspect 
that
could cause problems.   The intended environment for the ldm is one in which 
the user
ldm owns the required files and directories, and the ldm is invoked via the 
user ldm.
ldm should own all the files except bin/syshuplog and bin/rpc.ldmd, which are 
setuid
root via make.    Although this may sound onerous, I would advise reinstalling 
the
software as ldm.   (The bright side is, every time you reinstall it it gets 
easier!)
Btw, did you use these instructions in building the ldm:
http://www.unidata.ucar.edu/packages/ldm/ldmSourceInstallList.html  ??  I'm 
assuming
you built it from the source code, is that right?

Is notifyme working for you yet?
