Sorry the output in the previous email left out some relevant detail.
See here that BOTH dl components were unable to compile with the 1.8.5rc2
tarball:
+++ Configuring MCA framework dl
checking for no configure components in framework dl...
checking for m4 configure components in framework dl... libltdl, dlopen
--- MCA component dl:dlopen (m4 configuration macro, priority 80)
checking for MCA component dl:dlopen compile mode... static
checking dlfcn.h usability... yes
checking dlfcn.h presence... yes
checking for dlfcn.h... yes

configure: error: Cannot continue
I am getting this on ALL of my {Free,Net,Open}BSD platforms.
However, they all built the dl:dlopen component fine when testing Jeff''s
tarballs from PR410:
--- MCA component dl:dlopen (m4 configuration macro, priority 80)
checking for MCA component dl:dlopen compile mode... static
checking dlfcn.h usability... yes
checking dlfcn.h presence... yes
checking for dlfcn.h... yes
looking for library without search path
checking for library containing dlopen... none required
checking if MCA component dl:dlopen can compile... yes
The key difference I see is that dlopen() is available in libc, not in (the
non-existent libdl).
So it looks likely that something wasn't brought over correctly/completely
from master to v1.8.
