Hmm. This may not be pilot error. I build OMPI with a pre-installed
OMPI all the time and they don't conflict during the build (i.e., the
building OMPI always uses the libopen-rte and libopen-pal from the
build tree, not the install tree). Here's my link lines for ompi_info:
/bin/sh ../../../libtool --tag=CXX --mode=link g++ -g -Wall -Wundef
-Wno-long-long -finline-functions -pthread -export-dynamic -o
ompi_info components.o ompi_info.o output.o param.o version.o ../../../
ompi/libmpi.la -lnsl -lutil -lm
libtool: link: g++ -g -Wall -Wundef -Wno-long-long -finline-functions -
pthread -o .libs/ompi_info components.o ompi_info.o output.o param.o
version.o -Wl,--export-dynamic ../../../ompi/.libs/libmpi.so /users/
jsquyres/svn/ompi/orte/.libs/libopen-rte.so /users/jsquyres/svn/ompi/
opal/.libs/libopen-pal.so -ldl -lnsl -lutil -lm -pthread -Wl,-rpath -
Wl,/home/jsquyres/bogus/lib
Notice that libopen-rte.os and libopen-pal.so are explicitly mentioned
by absolute path name. Yours weren't. I wonder why...?

Libtool is 2.2.6. I use debian unstable so it's normally fairly
up-to-date, I suppose it's not impossible that a debian update has
broken things now that I think of it.
I normally build in memfs for speed and have just rebooted my machine
now, a full rebuild has failed again with the same errors.
All three symbols are shown as B according to nm so they should be
available.
Actually further testing shows it's user error again, if I remove the
current install then the build succeeds, it must have been pickings up
the libopen-pal from the install location rather than from the current
build.
