For some component it work as expected because on the revision 7106

-I$(top_srcdir)/opal/libltdl has been added to the AM_CPPFLAGS in the

between nearly every file in the ompi source code and the ldtl.h file.
Having to modify all the Makefile.am is a herculean task ...
First off, this is clearly a mistake. There are only a *very* small
number of files in the OPAL base that need ltdl.h. There's no reason
it should be a dependency for the majority of the tree.
I see the issue in the source code, and I'll fix it
(opal/mca/base/base.h, which is widely included throughout the tree,
has declarations of some internal functions).
Ah, ok, I was blind then, in thinking only the parts that compiled over
here used ltdl.h. There are a couple of ways to add include paths to
many Makefile.am's: You could leverage config/Makefile.options, and set
a default value for AM_CPPFLAGS (surely you have to change the
Makefile.am's once to only add to AM_CPPFLAGS afterwards; or, maybe
better, to add some other variable CPPFLAGS_LTDL set in
Makefile.options).
I'll add the relevant -I's and fix up all the remaining #include
statements while I'm at it (there's a few places where ltdl.h is
included).
