Gaa! While replying to Bob's comments on this thread, I took a closer look at the SCTP BTL Makefile.am and realized that there we had an error in there -- it was missing specifying the dependencies in the static / convenience library case. Once I fixed the problem, the libsctp dependency rolled up properly into libmpi and everything was fine. Sorry for the false alarm!

Here's the details, if you care...

The issue is that we actually have to have the compilation specified for each plugin essentially twice in its Makefile.am: once for the standalone DSO mode, and once for the convenience library mode because the target names are different. Here's the targets for the SCTP BTL, for example:

- mca_btl_sctp.la for DSO mode
- libmca_btl_sctp.la for convenience library mode

The issue was that the libmca_btl_sctp.la target was missing the LIBADD that specified the dependencies (and in my original mail, I was looking in mca_btl_sctp.la, not libmca_btl_sctp.la).

So -- ignore this "bug" report... sorry for the noise...

I meant adding --debug right after ../../../../libtool.
Could you rerun that, please?

Ummm... right.  Duh!  Sorry about that -- see attached.
