The Makefile constrains the set of symbols exported by the various
libraries.  That confuses some linkers, including mine.  IMO we need to
resolve the issue (no pun intended) before the 0.63 release.  

After running ./configure, I run this little script:

for T in src/*/Makefile
do
        sed 's/-export-symbols-regex.*$//' $T \
        | diff -u $T - | patch
done

It looks for "-export-symbols-regex" in the Makefiles, and deletes from
there to end of line.  That unconstrains the exported symbol list, which
should make your linker happier.  

HTH.
