How do I debug this broken link?

[Bruce Korb]

The problem is with xml2ag:

> $ for f in autogen getdefs columns xml2ag ; \
> > do echo $f; \
> >    ldd /usr/local/bin/$f | fgrep libopts.so ; \
> > done
> autogen
>         libopts.so.25 => /usr/local/lib64/libopts.so.25 (0x00007ff4c0168000)
> getdefs
>         libopts.so.25 => /usr/local/lib64/libopts.so.25 (0x00007fcc0c618000)
> columns
>         libopts.so.25 => /usr/local/lib64/libopts.so.25 (0x00007ff7ff680000)
> xml2ag
>         libopts.so.25 => /usr/lib64/libopts.so.25 (0x00007fc6c4918000)

The source Makefile.am uses "libopts.la" the same way as other executables:

> $ fgrep _LDADD {getdefs,xml2ag}/Makefile.am
> getdefs/Makefile.am:getdefs_LDADD   = $(top_builddir)/autoopts/libopts.la
> xml2ag/Makefile.am:xml2ag_LDADD    = $(top_builddir)/autoopts/libopts.la 
> $(LIBXML2_LIBS)

And the Makefile's themselves look reasonable:

> getdefs$(EXEEXT): $(getdefs_OBJECTS) $(getdefs_DEPENDENCIES) 
> $(EXTRA_getdefs_DEPENDENCIES)
>         @rm -f getdefs$(EXEEXT)
>         $(AM_V_CCLD)$(LINK) $(getdefs_OBJECTS) $(getdefs_LDADD) $(LIBS)

> xml2ag$(EXEEXT): $(xml2ag_OBJECTS) $(xml2ag_DEPENDENCIES) 
> $(EXTRA_xml2ag_DEPENDENCIES)
>         @rm -f xml2ag$(EXEEXT)
>         $(AM_V_CCLD)$(LINK) $(xml2ag_OBJECTS) $(xml2ag_LDADD) $(LIBS)

What should I be looking at to determine the cause of the brokenness?
Thank you!
