This specific problem may be due to a bug that Brian just found/fixed
in the configure script last night (due to a bug report from Paul Van
Allsburg). Could you try any nightly trunk tarball after r14600 (the
fix hasn't made its way over to the 1.2 release branch yet; I assume
it will soon)?

So I think you're having 2 issues (right?):

1. The opal missing symbol when you compile dynamically
2. The dummy/ranlib arguments in mpicc and friends

#2 may be fixed; #1 will require a closer look (per my previous mail).

Building from SVN will require more recent versions of these tools
(libtool in particular) -- see:
building.php. The HACKING file has good instructions on how to get
recent versions of the tools without hosing your system: http://
